Boss Bane Perk Effect
Boss Bane increases the damage you deal to bosses by the perk value. However, it also increases the damage you take from bosses by the same value. This makes Boss Bane a high-risk, high-reward perk for boss-focused combat.
The supplied perk data notes that Boss Bane affects any enemy with large health bars. Because of this, the perk is best understood as a boss-damage perk rather than a general farming perk.
Boss Bane Availability and Range
Boss Bane is listed for weapons and pets. Weapon rolls have a higher range than pet rolls, so the perfect weapon version is stronger than the perfect pet version.

Weapon | Weapons | 10% - 30% |
Pet | Pets | 5% - 10% |
Perfect Boss Bane Rolls
A perfect Boss Bane roll is the highest value in its range. Since weapons and pets have different Boss Bane ranges, they also have different perfect rolls.

Weapon Boss Bane | 30% |
Pet Boss Bane | 10% |

Boss Bane Strengths
Boss Bane directly increases damage dealt to bosses.
It is useful when the main goal is boss damage.
The perk has clear perfect rolls for both weapons and pets.
Boss Bane Weaknesses
Boss Bane also increases the damage taken from bosses.
It is not a general-purpose mob farming perk.
The tradeoff can be risky for players who struggle to survive boss attacks.
Is Boss Bane Worth It?
Boss Bane is worth using when a player wants more boss damage and can handle the extra damage taken from bosses. It is especially relevant for boss-focused builds, but it may be less useful for normal mob farming.
A high Boss Bane roll can be strong for boss content, but players should consider survivability before using it. If boss attacks are already difficult to survive, a safer perk may be more comfortable until better gear or a better build is available.
