Ok, that's it. This Prince and his so called army are... really good. I really need to change my tactics. I read Kerkes's EDE writing and tried a similar tactic, but no avail.(The writing was awesome btw.) My party doesn't seem to be capable of delivering enough damage to golems before they are overwhelmed by rakshasas' ADHWs and DBs. There are just too many of them.

Here's my party composition;

Vagrant Level 36
F/M/T Level 20/18/23
Inquisitor Level 35
F/M/C Level 19/18/20
Auramaster Level 40
Imoen Level 31

I have also a lot of good equipment; JD, FoA+5, FoDW+5, Answerer, Grandfather of Assassins, Staff of Ram+6, Dragon Lord, Holy Avenger, Hammer of Thor, Golem Slayer etc.

-How can i use contingencies and sequencers most efficiently for this specific battle? Or should i use them at all?

-To whom should i concentrate my attacks first?

-Despite her high level, my Auramaster was not much efficient (or i can't use her efficiently), any ideas for her?

-Summons and pre-buffs.

-And everything else that can help..

One strange thing; I keep Imoen out of the battle and cast Wish constantly. However her choices (19 WIS) are much worse than the ones my protagonist (16 WIS) gets (via JD). Did this happen to anyone else? Sometimes i find myself casting a Meteor Swarm on myself.
