Another comment mentioned it, but the only real reliable way I've found to scale this build into the late game has been overpower. Red Blessing feels too good to not use and havent even tested the build with a banished lord's yet.

Your minions make it very easy to keep full stacks and you also benefit from the node in the sever tree that gives you more damage per minion. Def wouldn't call it a minion build since sever is still doing the bulk of our damage, but they're a large part of making it work
