The final boss on the first act really showcase what it means to be tactical to beat the boss and how the tactical mode boss fights are way more than just bloated stat.
I stalled near the stair and immediately took out the gheist first since it's the one that can potentially insta kill a teammate. I had an oil wall to prevent them from approaching without getting slowed but that was quickly ruined by a phoenix dive so it only lasted for one turn (good enough, got the Gheist killed)
A few turns in, Fane was dragged in to his death (darn teleport on enemy metamorph) and the voidwoken spawned. It seems like a loss was inevitable.
But then I remembered that teleport was broke as fk and was abused in the "battle showcase trailer" so I jumped I repositioned my archer with Tactical retreat, used the left over AP to res Fane into a spot with no LoS with everyone running out the entrance to circle around to the side and healed with items while the enemies were occupied with the worm. (Doesn't need to press retreat. They just headed over to the worm if you're far enough.)
And after ressing and healing Fane, I did this.

I teleport Dallis dafk away from the fight and used the slow field on him before using the free AP from the pawn to hide and prevent any netherswap. This removes Dallis from the fight for like, 5 turns and combined with the help of the Void worm, I was able to do this in 1 go because the ridiculous aura boss wasn't in the fight anymore. His aura is the biggest trouble in that fight. Ridiculous stat with +50% damage on top of the difficulty 50% boost. Fun part, my teleport is already up again so even if I fail to kill all the magisters in time, I can still teleport him out once more and force him out of the fight.
This is the kind of fight I will never get to have in classic or explorer because of how threatening the enemies key targets are that I must remove them from battle either through death or method like this.
You can't call this cheesing either because the trailer they use completely support this to showcase what kind of creative method you can try to beat their hard fights.And if anyone is stuck on that boss fight on Tactical, try this method. you can easily position anyone with high wit to the same area and get a turn before Dallis does. Just use your glove of teleport and an oil scroll/grenade something and get back to your battle where Dallis won't really be participating until everyone is dead.
And if you're just the kind to get rekt and complain that "bloated stats got me killed! You cheated to win!", you aren't fit for this kind of mode.
