100% lifesteal is gonna be like 1-2 life per attack against trash your level with 0% monster difficulty...
But if you fight EPs your level or higher, it will work at 70 - 100% of what it says

EDIT: So yes it's useful for soloing, but not worth stacking instead of other more beneficial properties imo. In whistle-climbs its benefits are practically non-existent

Nope, need more magic luck.
Vouch, this is a way better side mod to stack to 25
