Adds missing checks to cain & abel (#90777)

## About The Pull Request
cain and abel could be used while they were in your pocket and that was
a bit funny
## Why It's Good For The Game
i shouldn't be able to swing my daggers while they're shoved inside my
pocket
## Changelog
🆑 Goat
fix: Cain and Abel (the colossus drop) now require you to hold them to
be able to swing them around
