Default comment of some of them sound interesting ideas, though again a shame to burn up some concepts on this (eg. javelin) instead of making them the basis for an entire class/weapon type, and many of them involve extra sprites and more on-screen mess/clutter.
And big dislike to giving assassin a slowing poison. It’s not a good thing for every class to be able to do everything, like we should be emphasising the differences not letting every class do speedy/slow/armourbreak/etc. smushing them all into one do-everything character lessens the point of having classes.
Farming: trying to get all 16, if it’s the same as the Oryx and Doorwarden tokens (click the stack to hatch the item at random), relying on RNG is going to be very annoying, like it was to get the April Fool abilities, so a bit of a plea to make it Exchange a Stack at the Tinkerer instead. Or some way to exchange duplicates, like a Tinkerer quest to hand in any of the 16 abilities and receive another stack back, to rehatch.
For reference, it took me over 50 white bags to get all 15 Mistake abilities and I heard many worse stories from others, 50+ hatch attempts would be 750+ tokens needed. So I mean if that’s feasible because they’re in many drop locations letting us achieve it without chain dungeons, then okay that works too. But it does leave a bad taste to have to repeatedly see duplicates when you only want the one most prized to you.
Edit: sounds like they do intend alternate methods of earning them:
Thank the Mad God!
