Poe ninja, link you account so can link your build and people can give helpful feedback

Without seeing your gear, supports, and tree, it’s hard to know what the issue(s) are.

If your gear is atleast on level (or even slightly under your level) and your gear has atleast a few good stats on it, you shouldnt really be having that much of a hard time with those bosses.

You are either way under geared (and if so, you should either try and farm/buy better gear), or your “build” isnt correct, or your supports are bad (all of the above, maybe?) Ember fulsaides (I think I spelled that wrong) by itself should pretty much melt those bosses… also, why wolf minions? If you want minions, you should be focusing on the fire skull minion, or some other spell based minion that jives with your build better.

Link your POB/poeninja profile. No one can really give you specific advice without seeing your character.

Are you following a build guide? It seems that your damage is low. You should be able to clear the campaign relatively easy with little investment. Path of building is a great tool for checking your dps and verifying upgrades.

Also, if you link your account to poeninja you can share your build with everyone and are much more likely to get help. I think fire scales with ignite and elemental/spell damage, so that is probably what you should concentrate on.

Fireball with living bomb for extra clear and infusions is a valid way to get to maps. Assuming you are using firebal (being the most relevant fire spell, tbh), we have to assume you have an issue somewhere with the build itself, whether that be support gems, gear, or passive tree. Without more info, it’s hard to say exactly. Generically, make sure your spell levels are levels up with the highest skill gems you have access to, make sure you’re using a staff or wand with + to spell kills (either all spells or fire spells), make sure that same staff or wand has some spell damage on it also (fire spell damage also acceptable). Focus on one defensive method (top of the tree scales energy shield the easiest), make sure you are wearing gear with decent resistances and defensive stats. Check your vendors for these items - the vendors in your act are best, but if your gear is particularly bad then older acts might still have upgrades for you too. Make sure your support gems are giving you damage or clearing ability, generally the utility support gems are a waste until you have a ton of damage or have some specific, build defining interaction from them

If you are playing trade league its possible improve your gear, since you reach act 4.Use trade for that and Ange to buy some craft currency.For Staff check out for some with plus lvls fire skills

If your not using synergistic skills and just using every fire spell you see then you probably need an actual build play I doubt your support gems or passive tree is any good let alone your gear

Have you tried turning the monitor on?
