How Batty!
How Batty! is a mod that changes every enemy’s AI to bat-random. Even shopkeepers!

Not intended as actual advice.
It also removes Luck immunity to bat attacks! Shopkeepers are excluded from this removal, though.
This page is updated for version 1.0.0 of HTF. As of this writing, there is no console-approved version.
Options
There is one option in the Custom Rules. The “Remove luck” option can be turned off to make a Lucky Charm basically break the game (making you immune to any enemy that has another place it can go).
