any help ? would appreciate any advice

You probably just lack enough damage I looked at your gear and it seems pretty meh like for example one of your weapons basically only has cast speed and 20 increased damage on it's rolls. You also don't have mana rolls on your boots or gloves so that's a bit of defense / offense your missing out on. I think if I was you I'd focus on upgrading weapons first probably will make the biggest difference in your damage. You can probably just spam essence of woe and come up with something better fairly cheaply.

thank you very much i will try doing that just need to farm some currency

which one kills you? start with that one and try to DPS it down then kill the other 2. you probably rolled some bad map mods also as your build should kill them pretty quick unless you rolled bad map mods

Cap your chaos res. One of the guys, i think maligaro, uses chaos AOE spells. With t17, damage mods and your 25% chaos res that's a recipe for disaster.

also consider just running a different t17 layout. Fortress is the easiest boss for most people.

Map mods are a pain for that boss. Try to avoid Increased AoE/Multiple projectiles mods, in addition to the regular mods like -max resists, no defenses, etc.

If you have capped chaos resist, don't bother to dodge all the spinning blade vortexes, focus on avoiding Shavronne's barrage and Doedre's AoE.

Usually I kill Maligaro->Doedre->Shavronne, each of them is annoying in it's own way when is dead. Last phase is the easiest.
