That house was sick. Pool table, bathtub, toilet. Actually a hideout.

First things first, temper your expectations. You probably will not get this build to wave 30 regardless of how much you invest in it.

Second question: are you following a guide? Your pathing and build choices are very suspect. For example you take 5 points on your way to the suppress cluster when you could take 4 going straight. You also don’t take the life wheel which is right there and instead path to marauder life which costs a ton of points. And there’s a ton of unallocated 2 point jewel sockets.

For gearing, every piece of your gear sucks and needs to be improved. The most straightforward thing is get a divine/eternal life flask. Hallowed won’t heal enough with a 4k life pool. After that, I’d question the choice of using a staff. Cold iron point + shield for example would be way more damage and way more defensive.

In the last demo at exilecon he took a role like Sin where he was guiding the player to fight the seed of corruption and save Wraeclast. His mannerisms and design are a lot more reminiscent of Shaper though.
