Certain things that inflict damage to the user (Screamer, as far as I know, possibly things like Poison Bite and Skyburn?) cause you to lose momentum for hitting your own resist.

Also not entirely sure, but apparently having dark resist might make Etacof take momentum from you?

Lemme know if there's any other self-inflicted damage that lowers momentum on a resist, I guess.


Relevant Balance Fu material:

Can frayed Voidgates not cost you momentum for hitting someone? It feels awful for someone to be able to cost you half your turn for 7 rounds by standing next to one.

Poison Bite doesn't inflict Poison damage, so Wyverntouched can't ruin their own momentum.

As for the spoiler: No. You're getting 7 Rounds of free, constant and most importantly potent Darkness damage, which can be used to gain Void Energy and be detonated at any given time that you can use a certain skill. That is far too good for the user to be cheating their way out of Momentum loss.

This has been corrected. As for the Voidgate thing, I don't think so.
