I started Chieftain using both some attacks and holy flame totem and flamewood support. Sometime later later I really wanted to go the melee ignite route with controlled blaze and sadism, but damage was lacking. All in all super slow getting through the campaign.
Getting into maps I switched to Boneshatter (the build I wanted to do initially). Immediately felt much better, getting into yellow maps in a four link so far, still lots of room for improvement, I am somewhat optimistic. Lots of cool tech for hitting one self, such as recoup, endurance charge generation and self ignite.
Haven't really used the league mechanic too much. I can't really tell why I am either absolutely crushing it or being crushed, there seems to be no in between.
And finally I am really sad about the Guardians Blessing support. Can't be triggered, hard to impossible to keep your minion alive and you have to reactivate the aura manually. Ouf. Let me know if you found any good way to use it.
But I am having fun.
How's your league going?
I didn't try anything with Guardian's Blessing so I don't know the specific mechanics of it, but it might be something to use with Minion Instability. Or an Animate Guardian with ES buffer can potentially be a good target for it. Just spitballing, I'll probably never use it.
Minion instability will let it pop, but you will still need to manually resummon and reactivate the aura. Animate Guardian could work, the wiki states that there is some possibility with masked of the stitched demon. Maybe I'll look into that. I hope they patch it so that the minion can be summoned with the aura being active.
