An excellent batch of treasures! All very unique and well designed. They feel straight out of the Heroes book.
The single piece of critical feedback I have is that Summer's Canticle having a temp stam features feels a bit odd when its the main gimmick of Blooming Shillelagh. Works perfectly fine as its own item, but doesn't seem right when part of the set, if that makes sense.
Otherwise, I've got a Green Elementalist seeking out a powerful staff in my campaign—and I know just what to give her now. Thanks for the loot!
