Is this a bug or is it supposed to happen? - Myers
So, I head that to do the Evil Incarnate achievement, you don't necessarily need to use Tombstone on all four survivors, you just need to mori them in any way. Well, I did get a 4k mori only with Devour Hope and the Ebony Mori, but I didn't get the achievement. Is this a bug or am I missing something?

You heard wrong. You have to use tombstone. Other moris don't count. It would be SO much easier if all you needed was a red offering.
Is this achievement available on the Switch?
Be interesting to see Inf Tombstone Myers with the latest buffs, but yeah Glint got in first, only Tombstone Mori's count for Evil Incarnate.
Is pretty hard to get now, though I wonder if it might be easier to Tombstone Piece survivors for the achievment now... at least it is actually possible to do unlike before.
