- Have Sunblood Amethyst equipped as a Night Fae Resto Shaman
- Use the Amethyst on a target, start channeling Fae Transfusion before the Anima Font hits you
Result: Once the Anima Font hits you, your Fae Transfusion cast will be interrupted.
It doesn’t seem to interrupt normal casts like Healing Wave, and I even tried it with Far Sight to see if it was with channels, but that one worked correctly also. Seems to only be a problem with Fae Transfusion.
