The new **Boosts System** introduces new expedition-boosting buffs that make each expedition feel different and more exciting. Boosts are **random consumables** that drop while you play (skilling, killing monsters/players, or opening Mystery Objects). They can only be used during the current run, and vanish to dust on death or entering a safe zone. Important rules: * Boosts **only work for your current run**. * They **disappear** if you die or enter a **safe zone**. * High-tier boosts - especially **Tier 4 -** can temporarily turn you into an **absolute monster** if you manage to get multiple of them over the course of a run ## Boost Types There are 9 Boost Types, each with 4 Tiers of effects. * Strong Ale - reduces stress by 10/30/50/200 * Lucky Charm - increases current reward multiplier by 5%/15%/35%/100% * Rabbit's Foot - increases reward multiplier by 250/500/750/1500 * Body Rune - reduces incoming damage by 4%/12%/25%/50% * Relentless Fury - increases attack speed by 5%/10%/30%/50% * Unshackled Power - increases special attack regeneration by 10%/25%/60%/100% * Cosmetic Wealth - increases artifact drop EV by 5%/10%/20%/50% * Bounty Gather - adds +X% chance to gain additional resources per action * Overclock - increases skilling speed by 3%/8%/16%/35% ## How to Get Boosts drop through a variety of methods during your expedition: * Skilling * NPC Kills * Mystery Objects * Player Kills ## Boost Tier Whenever a boost drop is triggered, it rolls a Boost Type, and the Boost Tier * T1 - 50% * T2 - 35% * T3 - 13% * T4 - 2% Tier probabilities do **not** depend on region, source type, or zone tier.
