Amusing Easter Druid Bug
I received the Easter Druid hat and have noticed an amusing bug with it. Its passive ability is a 15% chance to deal a 50% increase in healing. Fine. Way cool. But the neat thing is that if you use Easter Druid once in Arena, then switch to something else, say Witch, Witch also has a 15% chance to deal 50% increase in healing. This opens the possibility of all sorts of benefits, like using Sweet set with Blessed set to fully restore your banner with one turn.
For example, Witch/Nightmare for me, after using Easter Druid can deal around 20,000 health (normally she is 13,000). It's a huge help against those cursed teams with the mythic time jump emblem.
Of course, if you didn't get Easter Druid, this is of no use to you. But the lesson here is that I doubt Rovio/Chimera have fully tested for all of these sorts of bugs, and I bet with all the new classes and abilities there are other crossover things that might be helpful. Maybe we should start a thread of ones we find?
