POE - Boneshatter of Carnage Champion is the Stunningly OP League Starter You NEED to Try in [3.26]

Act 1: Start with Frost Blades linked to Ruthless and Ancestral call Support till you get to merveil. Then After reaching Merveil's Cavern Switch to Infernal blow with same supports. Act 2: After you alocate Tribal Fury and take the Strike mastery for additional target swap out Ancestral call with Rage support. Use warlord's Mark on targets to generate Rage by stunning them. Make sure to help alira for resistance. Act 3: If you are missing too much accuracy by this act start using Precision for accuracy. Switch to Boneshatter after killing gravicious, purchase it from cleresa. You can attempt first lab after you hit level 30 and have all trials completed before killing dominous. Act 4: Grab Berserk as reward after completeing the deshret quest, only use it when on full Rage. After you find a 4-link swap out Rage support with Brutality and add Trauma support after killing Kaom and Daresso if you are using Boneshatter of Carnage otherwise use Behead support with normal Boneshatter. Make sure you have Veteran's Wrath allocated before making the above change. Act 5: Once you allocate Resoloute technique (keystone) you can get rid of precision. When you finish Act 5 you will get -30% all resist so craft resistances in all your open suffixes from crafting bench. Act 6: On starting act 6 take the Purity of elements, keep it level 1 only. You might face some mana problems while using this and Pride together. You can start using Collasal Fist for a bit more additional damage by allocating Arsenal of Vengeance keystone, this is not required at all its just something if you wanna use. Act 7: Attempt Second lab on completeting the trials in this act, should be easy enough. Remove the fortify mastery after taking fortitude. Act 8: Nothing to add for this act, but if you find the Ironwood tincture like i did you can start using as its quite good for this build. Act 9: Nothing to add for this act either, just follow the skill tree, look for any masteries i might have allocated later. Act 10 and maps start: Complete your 3rd lab on finishing the trials in this area. Before starting Maps make sure to have atleast 50% all resist (excluding chaos resist) Quality your weapon to max.
