The Warriors are sick of other heroes stealing the spotlight, so they're bringing their A-game! For the next several days, all normal and slow speed Warriors will gain the retaliate ability! There are also lots of quests to complete, including a special quest chain that will allow you to earn the Dragonkin Squinch skin if you don't already own it (or 3 Heroic Summons if you do).
Could Squinch actually be a dragon?! (Spoilers: No. Squinch is a goblin. But he likes pretending to be a dragon, and Ferno seems to enjoy having a buddy to set people on fire with.)
