Is it just me or does lifesteal just not function in any form on bosses? I’ve tested dozens of different sources and none of them seem to work on purple mobs. Is this intended?
Bosses have an innately high resistance to life leech. However, you can lower this resistance with skills that lower all resistances and get some amount of life leech. It is smart, however, to supplement your staying alive with some other forms of health regain.
