I have 3 healers, all of which are not healing...
Is there a reason why not?
Healing is disabled against Daemon (and Eclipse and Aboxalypse).
Because Daemon is built so no one can heal against her. This thread, http://www.subeta.net/forums/view/727080, can help you out when you want to see what challengers have things like healing turned off. It also lists what all their weapons do, which can be helpful.
Thanks for asking that i was thinking same thing and never asked.
