I understand why fun-loving barbarian, attention-needing bards, and drunkard clerics all rest and recover charges in taverns like shrines.
What I don't understand is why studious artificers and scholarly wizards don't recharge clickies etc in crafting halls.
I propose that the Cannith Crafting Hall count as a tavern for purposes of healing and restoration. I wouldn't be put off by a smoothie stand or bind point either.
