Teratotaur doom mechanic

[Mhaeric]

It's not really "cheating" any more than LoS'ing the big golem with pillars in AK first boss, Imminent Catastrophe on last boss, Garuda's Mistral Shriek/Song, among others. There's a reason primals/coil battlefields are flat and featureless.

I would say it's more akin to standing in the tree in the first AK battle to avoid attacks. Being on top of that rock is not visually out of LoS like with the examples you mentioned, nor is it clearly a spot that is meant to be stood in to avoid an attack. It is pretty obviously an unintended quirk of the battlefield, and I suspect it has a high chance of being fixed by SE.
