So far I want to build for Extreme difficulty and if possible Act 4 Extreme.
My Team Lv 37 (Preparing still haven't haven't been on Extreme yet) --------Warrior Mage-Warrior --------Cleric ^ that's how my battle formation is
Equipment Warrior 1 : Annihilator Set with Golden Axe and Strength Cape/Ring Warrior 2 : Sovereign Set with Epic Spear with Strength/Endurance Cap/Ring Cleric: Eccelsiarch Set with Dwarf Lords War Hammer with Intellect and Endurance Cape/Ring Mage: Aetherweave Set with Luminescent Rod with Intellect Cap Ring
Explanations
For Warrior 1: was thinking of using the Executioner for crit damage I probably building my second warrior all wrong.. I was thinking of giving his Epic set to the cleric since it helps the cleric out more though unsure.
I wanted the Cleric to be focused around on Stun Chance % with his Aoe Spell. Attempt to Stun Lock the opponents.
As for the Mage: since its protected most of the time and hardly ever targeted for some reason. I decided on Full Int...
Eh..... Any advice.. would be great. Even if I have to 100% change everything.. (stats Sets and all that). Thanks much.
I don't find Epic Sets all that useful. Act IV is survival, so Health/Power after the battle isn't going to help you.
I prefer to build the Champion (and Cleric) with Health Regen equipment, one-handed weapon, and shield. Rubicite Breastplate and Martyr's Signet would get you (4*Tier + 5*Tier) health regen. At 37, that's 117 health regen at Tier 13 for both.
Supposing you have the items:
Steel Sentinel's Pauldron's are good for 65% chance of +.20 action for on-hit.
For Shields, Doomwarden gives +5*Tier Retaliation and +5*Tier Bonus when Healed Knight-General's Aegis gives 75% chance of +30% Damage Protection on-hit Stalwart Protector gives +3*Tier Health Regen and has more defense than other shields at the same level
Equip whatever Blue items and Purple Set items for Hands, Legs, and Feet, since there aren't any unique Epic items for those slots for some reason.
If you go with a Headsman's Man Standby for your Champion, you can equip a Black Flag of Dilaera for 9% chance of 250% crit damage (~500 damage at Tier 13, more if your strength is higher.). Throw in some Shards of Dilaera and do even more. With the Steel Sentinel's Pauldrons + Shield Wall skill + Health Regen, you'll be hitting more often while soaking damage and occasionally dealing large hits. Shield Wall uses quite a bit of mana though, but with the Black Flag, the Champion should still get targeted fairly often.
