Dropped by Morille Mortelle, a 82~83 NM in Crawlers' Nest [S]. Duo or trio is recommended as it hits very hard and fast. Spams Dark Spore for 1k and a new AoE ability that wipes shadows and transfers debuffs from the NM to nearby players.
Having this hat gives the option of putting a stat other than pet haste on the MKE hat. If you are a BST main, this is huge. Use this hat for pet offense, and the MKE hat for pet def/regen, and you have the possibility of building 2 respectable idling sets. In the grand scheme of things this may not seem important. But if you do all pet endgame events, having a pet offense set, pet defense set, and a decent reward set can make a huge difference.
Well the point has been made for BST and PUP, but I actually wouldn't mind this for soloing on DRG(not for breaths of course). 5% haste would mean more wyvern tp, which would also mean more potent cures. Now I'm sure this amount could be next to negligible, but any bit could help yeah?
