February 11, 201511 yr Expected Result: I don't think Frightening Roar is supposed to interrupt, as it does no damage.
February 11, 201511 yr I've noticed several examples of non-damaging spells that cause an interrupt as well. I'm not too familiar with the names, but I believe the level 1 mage spell, Arkham's Dancing Lights or something, has an interrupt effect. Infact, I think Barbaric Yell has an interrupt as well. I don't think it's a bug, though.
February 11, 201511 yr Author It is a bug I think, I reported the "interrupts occur on non-damaging spells" bug a few patches ago (which was acknowledged by QA). It may be something designers have to edit manually so that's why it now doesn't happen on everything. Edited February 11, 201511 yr by Sensuki
