Something I think the community is skipping over when it comes to Curse of Nihility So the DL team has effectively dropped a bomb on us today with the announcement of the Curse of Nihility that will be present in the RotSD quests. 

At the top of the article where it was announced, it's stated that it will affect units for "A certain amount of time" and it won't be present for the entire quest. This could be a mechanic similar to Tartarus' Fury of the Fallen, where it can be disabled relatively quickly. On the other hand, it could take up 50% of the quest time and could make a bunch of units near unusable.

I'm hoping that it's the former instead of the latter for obvious reasons but who's to say
