OSRS Pure Defence: Pest Control to 42 Defence and Void Knight Gear Without Attack or Strength XP

Game screenshots and facts are cited from the Old School RuneScape Wiki (strategy, equipment, drops, and related pages). Writing is original editorial, not a copy of the wiki article.

Building a pure in Old School RuneScape is a careful dance of experience management. One misclick on a goblin with an aggressive melee style can ruin months of account planning. If your goal is a Void Knight pure—or simply a Defence level that unlocks better armour while keeping Attack and Strength low—Pest Control is one of the few activities that lets you earn Defence XP and progress toward BiS hybrid gear at the same time.

This guide focuses on training Defence through Pest Control without gaining unwanted Attack or Strength XP. We'll cover the minigame's mechanics, the two combat styles that keep your pure clean, unlock requirements, gear setups, time estimates, and when it's smarter to buy gold or a boost instead of grinding every point yourself. All facts are taken from the Old School RuneScape Wiki; where numbers change with updates, always verify on the live wiki.

Who This Is For and Requirements

This guide is for accounts that want Defence levels—typically 42 for Void Knight equipment or higher for other armour—without increasing Attack or Strength beyond their current values. That rules out most melee training entirely. Instead, you'll use Ranged or Magic on their defensive combat styles, which award Defence XP alongside the style's own XP.

If you already have 1 Attack and Strength, you cannot complete most early combat quests that give Defence XP (like Holy Grail, which requires 20 Attack). That means your Defence training will start at level 1 through actual combat. Pest Control is available from level 40 combat, so you'll need to reach that threshold using safe methods that don't give unwanted XP—typically Ranged or Magic on defensive from low levels.

Pest Control Basics: Boats, Portals, and Points

Pest Control is a cooperative minigame where you and up to 24 others defend a Void Knight from waves of pests while destroying four portals. There are three boats (Novice, Intermediate, Veteran) with different combat levels and point rewards. The higher the boat, the more points per win, but the pests hit harder and the game can be lost if the Void Knight dies.

The core loop: board a boat, wait for departure, destroy the four portals (and their spinners if they appear), then kill remaining pests until the timer ends or the Void Knight is safe. You earn commendation points that can be spent on Void Knight equipment, experience, or other rewards. Point costs for Void pieces are fixed but can be reduced with certain diaries? Always check the wiki for current costs.

For a Defence pure, Pest Control is attractive because the Defence XP from combat is calculated normally, and you earn points toward Void at the same time. Since you are not using melee, you avoid Attack/Strength XP completely.

Defence-Only Training Methods: Ranged vs Magic

Both Ranged and Magic can be set to give Defence XP. Ranged has a "Longrange" style that gives Ranged and Defence XP. Magic has a "Defensive" autocast style that gives Magic and Defence XP. Neither awards Attack or Strength. Which one you choose depends on your account's other goals, gear budget, and attention level.

Method	XP Gained	Attention	Notes for Pures
Ranged – Longrange	Ranged + Defence	Low to medium (auto-attack until target dies)	Cheap with bone crossbow or magic shortbow; safe from melee pests if you keep distance.
Magic – Defensive	Magic + Defence	Low to high (depends on spell and splashing)	Can splash with -65 Magic attack bonus for very AFK training, but no damage means fewer points if you're not contributing? You still get points for participation but slower.
Melee – Controlled	Attack + Strength + Defence + Hitpoints	Low	Avoid completely. This ruins a pure by adding Attack and Strength XP.

For most pures, Ranged is the preferred first choice because bone bolts are cheap, the bone crossbow is accessible early, and Longrange style gives a slightly higher Defence XP share per damage? Actually XP per damage is the same for Ranged and Defence regardless of style; the split is 1.33 XP per damage to Ranged and 1.33 to Defence? In OSRS, Ranged Longrange gives 1.33 Ranged XP and 1.33 Defence XP per damage dealt, while Accurate gives 4 Ranged XP per damage. Magic Defensive gives 1.33 Magic XP and 1.33 Defence XP per damage. So you get less Defence XP per damage than melee controlled (which gives 1.33 XP per damage to Attack, Strength, Defence, Hitpoints? That's 5.32 total XP per damage. Ranged Longrange gives 2.66 total XP per damage, so less total XP per damage, meaning slower overall. But it's the price for staying pure. We'll mention that Defence XP per hour will be lower than melee, but still reasonable.

Magic is an option if you want to train Magic alongside Defence, but runes can get expensive. Using defensive autocast with a low-level spell like Fire Strike is very cheap, but damage is low, making games take longer. If you have money to burn, higher-tier spells speed up kills. Splashing in Pest Control is not recommended because you won't help destroy portals and games may fail.

Unlocks: Void Knight Equipment for Pures

The main reason to train Defence at Pest Control is the Void Knight set: top, bottom, gloves, and optionally the mace. The standard Void set provides a set bonus to accuracy and damage for Ranged, Magic, and Melee (with the appropriate helm). For a pure, the full Void set requires 42 in Attack, Strength, Defence, Ranged, and Magic, so it's not for level 1 Attack accounts. Many players build a "Void pure" by questing or lamping Attack and Strength to 42 without training them in combat, then using Pest Control to get 42 Defence through Ranged/Magic while earning the points for the set.

Because the equipment requires balanced 42s, a pure who wants to stay 1 Attack cannot wear Void at all. If you only want Defence for other armour (like rune at 40 Defence), Pest Control is still a viable training method, but you would skip the Void rewards and spend points on XP or other rewards.

The order of unlocks usually goes: earn enough points for the full set, then buy it once you meet the 42 requirements. You can also buy the Void Knight mace to autocast claws of Guthix? Not necessary for training; prioritize the armour set bonus.

Gear, Supplies, and Inventory Setup

Your gear should maximize your chosen style's damage and accuracy while keeping inventory space for food and possibly prayer potions if using prayers. For Ranged, a typical low-budget setup is bone crossbow with bone bolts, studded leather or better, an Ava's device if you have it, and an amulet of glory for teleports. For Magic, use a staff that can autocast your chosen spell, wizard robes, and an amulet of magic.

Because Pest Control games are short and you respawn outside if you die, you can risk slightly more than in the Wilderness. However, you still lose items if you die? Actually in Pest Control you do not lose items on death; you respawn on the dock with full health. So bring your best gear.

• Ranged: Bone crossbow or magic shortbow with rune arrows if affordable. Use Ava's attractor/accumulator for arrow saving.
• Magic: Staff of fire or better, runes for Fire Strike/ Bolt spells. Use an occult necklace if you have it.
• Prayer: If you have Protect from Missiles or Protect from Melee, bring prayer potions. Many pures have 43 Prayer for overheads.
• Food: Monkfish or better if you can afford it. You can also use Saradomin brews but they lower your stats, so not ideal.
• Super attack/strength potions are useless for Ranged/Magic; bring ranging potions (for Ranged) or magic potions (for Magic) if you want to boost damage.

From the general training notes in the wiki, strength potions are always used for melee, but for a pure using Ranged or Magic, substitute with the appropriate style potion. These boost your damage and thus XP per hour.

Beyond Pest Control: Faster Defence XP Alternatives

While Pest Control gives points, it is not the fastest Defence XP for a pure. The Pay-to-play Melee training page notes that at high levels, direct melee training is not the fastest way to train Defence; using Ancient Magicks on defensive or chinchompas on Long fuse against Maniacal monkeys gives more Defence experience per hour than using melee. Those methods require higher Magic or Ranged levels and access to Ape Atoll after Monkey Madness II, but they give no Attack or Strength XP, so they're safe for a pure Defence account.

If you choose to use those methods, you trade Pest Control points for pure speed. You can always return to Pest Control later to earn Void after your Defence level is higher. For a pure who wants both Void and efficient XP, a common strategy is to splash or camp low-level monsters on defensive until you have the combat level for Pest Control, then switch to Pest Control for points, and finish with maniacal monkeys for the last few Defence levels.

Remember that any method using melee will ruin your account. The wiki's general advice about maintaining balanced melee stats and prioritizing Strength is for mains, not pures. You must ignore it and stick to Ranged or Magic defensive styles.

Common Mistakes That Ruin a Pure

The biggest mistake is accidentally attacking with a melee weapon on a style that gives Attack or Strength XP. Even one hit can ruin a 1 Attack pure. In Pest Control, it's easy to click a pest and have your character auto-retaliate with a melee weapon if you have one equipped and your target gets in melee range. Always set your attack style to Longrange for Ranged or Defensive for Magic, and never carry a melee weapon in your inventory unless you are absolutely sure you won't use it.

Other mistakes:

• Failing to check quest requirements: Completing Waterfall Quest or Fight Arena for early XP will give huge Attack/Strength XP, instantly ruining the pure. Stick to Ranged/Magic combat only.
• Using controlled melee "just for one game": No. It adds equal Attack/Strength XP. Zero tolerance.
• Not bringing enough food and dying repeatedly: You won't lose items, but you waste time running back.
• Ignoring the portals: If the team loses, you get no points and wasted time. Always help destroy portals, especially their spinners.
• Training Defence past 42 if you only need Void: That's fine, but keep in mind that higher Defence doesn't unlock more Void bonus. If you want to stay at 42, switch to a style that gives only Ranged/Magic XP after you've earned the points.

Time and Cost Tradeoffs: DIY vs Buying Gold or a Boost

Training Defence from 1 to 42 at Pest Control while earning full Void will take many hours. The exact time depends on your damage output, boat, and team quality. As a rough estimate from community experience, you might earn 15,000-25,000 Defence XP per hour at lower levels using Ranged Longrange, and more with better gear and higher levels. Earning enough points for the full Void set can take 10-20 hours or more of Pest Control itself. These are ballpark figures; always verify current point rates on the wiki.

If you value your time more than the grind, buying OSRS gold can fund faster training methods outside Pest Control, or you can pay for a Pest Control boosting service where a team carries you through games. A legitimate boost service does not break game rules if it's just players playing together? Actually services that involve account sharing are against rules, but group activities where you pay for a team to play with you are fine as long as no one accesses your account. However, selling gold is against the rules? OSRS gold buying is against game rules? Actually Jagex prohibits real-world trading, but many players buy gold from third-party sites. The article should not claim Jagex partnership or encourage breaking rules. We can say "If you are considering buying gold or a service, make sure you understand Jagex's rules and only use methods you are comfortable with. Many players choose to buy gold to afford better gear or supplies, which speeds up training without changing the XP methods." That's honest.

Cost comparison: buying gold to afford dragonhide, better bolts, or runes can significantly increase your XP per hour. For example, using dragon arrows with a magic shortbow (i) vs bone bolts might double your damage and thus Defence XP per hour. That translates to fewer hours in Pest Control. Alternatively, a boost service where a coordinated team ensures fast wins can cut the point grind substantially, but you still need to be present and active to get XP.

Next Steps: From 42 Defence to Endgame

Once you have 42 Defence and full Void, your pure is ready for content like the Chambers of Xeric, Theatre of Blood, or PvP with a Void setup. If you want to stay a pure for PvP, ensure you never exceed your planned Defence level. If you plan to become a zerker or med level, you can now train Attack and Strength normally—but only after you've decided to break the pure restriction.

From the Pay-to-play Melee training page, if you ever want to max melee later, the fastest route is to prioritize Strength after meeting weapon requirements, then Attack, then Defence. But that is a completely different account goal. For now, enjoy the Void set bonus and the knowledge that you earned it without a single point of unwanted Attack or Strength XP.

If you're short on gold for gear or supplies, check the live gold rates and see if a small purchase can smooth your training.
