Soul Shredder Bullets

The debuff applied to opponents by Soul Shredder Bullets behaves differently from all other lifesteal items. It does not affect the user's Spirit Lifesteal stat, nor is it factored into the formula above; instead, it adds a flat +20% spirit lifesteal against an affected target while the debuff is active. For example, if a player had Soul Shredder Bullets, Enduring Spirit (+10%), and Leech (+35%), their spirit lifesteal against a target affected by Soul Shredder Bullets would be:

$L_{F}=[1-(1-0.10)\times (1-0.35)]+0.20=61.5\%$

Their spirit lifesteal against a target not affected by Soul Shredder Bullets would instead be 41.5% (equal to their Spirit Lifesteal stat).
