Fairly certain that you gain around 50 hp with every kill , no matter the origin . I want to note that this is your build , and I ' m giving you material for you to decide . I didn ' t mean for you to include everything I said , just that these are your options . If you have the Arstors Spear , for example , you wouldn ' t need the barbed sword . They are used for damage while still being tied to your build , they shouldn ' t be used for the activation . I realise I said a shit ton of stuff so it was likely overwhelming . If you ' re planning to be a pain in the ass , have relatively low vig , you plan on not being seen , so you shouldn ' t worry about being hit . Arstors Spear doesn ' t even have to be usable , I gave it as an example as if you wanted to have a more damaging weapon , but you don ' t really need the stats for it , as the healing procs either way . You can keep it on your back , just to get health back . If you ' re worried about the poison of the swamp , have a Blessed item , like a shield , in your left hand to regen health . If you ' re going to make a luck build , you ' re gonna need luck . Can ' t make use of the mercenary class . The bandit ' s knife and poison combo isn ' t the best for proccing , or activating the debuff , but it ' s good for keeping pressure . If you actually want to poison or bleed them , it ' s better to keep one Bleed Bandit ' s Knife and one Poison Ghru Dagger , and the Barbed sword for the take down . If you want to confuse your opponent , it ' s better to have a Poison Bandit ' s Knife instead . The name of the game is pressure . You will appear out of nowhere and cause panic to your host and summons . Here ' s a revised for ya . Notice how it gives you four extra levels to do what you want with . You can also have the Arstor Spear in your third slot when the host is killing enemies . I hope this helps .
