I can't win the quest yet - normal mode - no conso

ok so no enchants / no hex / no conditions.
"Spirit spam" & so (paragon ? didnt unlock them yet for this guy .. )
- can pets be usefull ? I think it can be nice, but didnt reach the boss with them, so i can't tell

- what is a working strategy, i must kill spirit ? I tried but seems kinda pointless they respawned all ultra fast...didnt kill the second the first was back (must equip 4 * spirit o fury ?) so i easily run of mana
- signet envs ?
- how many "healers" are needed, dont they have tons of mana problem?
- can we "DAZE" him for the win ?
didn't found yet any nice balanced team between skills for winning him vs skills for winning the arena (always loosing LAST wave of course, boring^^)
(I take any screen of team, of course)
thx for helping !
some other questions
- how many time is require for *the boss part only* ? 5 - 10 mins ? 30 mins if ultra fast ?
- ive read somewhere you can flag your hero away before taking chest and so winning 8 * the drops from chest ? True ? Does this work ?
- read somewhere a "door trick" : Still exists or it was years ago ? like begin in the room before killing the last monster, so door stay open
- read on wiki after you kill him lot of monsters spawn ...where do they spawn ?, is it hard, are you overhelmed / if you die - quest is done ?
or its kinda nothing & no danger at all (when i ll finish to kill him , i'd just like not to fail stupidly this long quest)
