I’ve personally found great effectiveness using cloud of daggers maybe more than any other spell. Funnelling enemies through a passageway with multiple cloud of daggers cast on the spot is probably my current meta. Then I utilize thunder wave/ black hole to keep the enemies on the other side of the daggers once they make it through.
Another thing if found amazing success with is getting a party to strength 20 as fast as I can, which then I find 90% of enemies can be thrown off cliffs for instant kills. Throwing enemies off cliffs also only requires stealth checks where the body hits the ground and dies.
Lastly there is a fun little cheese strategy I’ve picked up that I don’t see anyone talking about. If you cancel an improvised weapon attack with an NPC before you deal damage, you can move NPC’s without angering anyone.
Wall of fire has been great to me, as well as Thunderwave. My Warlock has it, my Astarion has it, my Shadow heart can summon a Djinni with it, and then Karlach can just throw almost any size monster off a cliff with her hands.
Honestly environmental kills trivialized a couple boss fights thus far.
What happens to the loot once the boss is thrown off the cliff? My fomo is keeping me from trying it. Where does it go?
That depends on the boss. The boss at the end of Astarions quest line can be trivialized by pushing him off, then he responsible a coffin for the second “phase”. The phase is trivial so you’ll get to loot him.
Yeah I refrain from using it in many situations but in the ones where it’s favourable, e.g. landing into combat surrounded by low level mobs, a single Thunder Wave can win the fight in the first move, just have to mop up the boss and any mobs that succeeded a saving throw and still get all of the more valuable loot
