[3.9] Durimon' Astral Projector Cold Shockwave Totem Scion, Easy and Safe Endgame, Melting Bosses

nope just watched video how it plays and saw something got knocked back ^^

Hi,i really like you'r build, i've just hit 72 and it's really cool to play.
It's my first totem build and as i see leech don't work for me but for my totem.
So how could you regen you'r es ( if the devoring diadem don't proc )after a big hit ( or after spamming totem, cause the cost is around 180 )
And how regen life? only flask and life regen?
Thanks !
