Good catch, the tag that's used for on-block effects snuck onto the move. I've already gotten rid of it on my end.
I'll fix up that and the other issues real quick. The catalysts aren't supposed to stick around; I went for an offensive approach in testing, so I must've beaten the Chess Golems too quickly to notice. (Their weaknesses actually open them up to quite a few different approaches!) The Protect Cape text and Sample talking to the Caretaker will also be fixed.
The Tengu's Turbo Togs are indeed a Touhou reference. Funny enough, though, I haven't actually played a Touhou game, I've just played Touhou Puppet Dance Performance and the Gensokyo mod in Terraria.
EDIT: Oh, right, the other question! War Shield Bash does deal damage first, like other attacks that lower block.
