Help with Volcanic fissure build

I'm using a Volcanic fissure of snaking chieftain build and I can clear t16 maps but I sometimes get 1 tapped by enemies. My boss damage is not that good and it takes a bit to kill t16 map bosses. I don't really know what to do with my build. I was also thinking of using a Vaal timeless jewel with immortal ambition to get more regeneration but I'm not sure if that would actually help. Any help with my build would be greatly appreciated.

chieftain is in the weird spot where it doesnt get the insane "free" dmg and speed that berserker does

you arent abusing fire max res to hit 90 all, so its difficult to really feel OP

you have alot of wasted tree nodes: double entrance from marauder, butchery wheel, strike range, the entire res wheel below it

your weapon is a very medium/low tier starting unique. get a 650+ pdps axe for 5c or less

all of your uniques except echoes are 1c/starter uniques. get the best rares you can afford with the highest armor, res, hp etc

your flasks are random: get granite, a source of onslaught (flask, hatchet mastery, cluster), then remove freeze/bleed/poison/whatever you are missing

regen is rarely the correct answer. it is an okay stat but for a slammer you want big damage and big defenses like armour and phys taken as element

redo your implicits on chest to get phys taken as, it is the most powerful defensive stat in game for lower left tree character
