Played on hard lvl 12 party Eder, Grieving, Drood PC, Durance, Custom Barbarian and Aloth, First of all the trash was so easy and didn't feel like epic lead up to the end, I rested before the Thaos fight but it really wasn't required, Run your entire party behind Thaos, send Eder to 1 golem and your other melee to the other golem while your druid and aloth cast abilities that do AOE knock prone, then unload your entire party on thaos he should die before he can stand back up, then tank and spank the golems and 30 seconds later you have won the game. I'll do a POTD playthrough later hoping it will be significantly harder than "hard" every fight is just AOE Disable -> AOE nuke with druid and aloth gg. Also scroll of paralize and Maelstrom GG.
