Berserker Tincture

A potent cocktail that boosts adrenaline and suppresses pain response, making you unkillable while increasing damage and speed for a brief period.
Overview

The tincture’s effects make it a decisive tool for aggressive engagements, last-ditch pushes, and timed bursts where surviving heavy incoming damage while maximizing offense is required. Because its primary benefits are survivability and combat potency rather than healing, it is used most effectively when combined with tactics that exploit a short window of overwhelming force rather than prolonged attrition.
- Primary effects: stimulates adrenaline, suppresses pain response, grants temporary immunity to death, increases damage dealt, increases movement speed. The effect duration is described as brief; no precise time or numerical values are provided in the available sources.
- Typical use cases: initiating fights, breaking enemy lines, escaping otherwise fatal situations while still dealing damage, and timed objective captures where a short period of invulnerability and speed gives decisive advantage.
- Tactical notes: deploy the tincture when you can immediately capitalize on increased damage and speed; because the invulnerability is temporary, coordinate its use with teammates or with abilities/items that extend or follow up on the burst window. The tincture does not restore lost health—its benefit comes from negating fatal damage during the effect rather than healing.
- Synergies and cautions: pairs well with high-damage weapons or abilities that have short windows of effectiveness. Avoid relying on it for extended survivability; once the effect ends the user returns to normal vulnerability. There is no source information about stacking, cooldowns, or crafting/availability, so treat each dose as a limited, consumable resource.
