As I posted about in the 'World 14 unofficial changelog' thread, current bat behavior does not match what the wiki describes. Loftar says they haven't been buffed, which implies either the wiki has been wrong all this time, or there is some bug. These are my current observations:
- Vampirism is used way below 50% yellow opening. They use it at least as low as 31% yellow opening.
- Vampirism does not heal 'a small amount', one bat I fought managed to double its HP in a very short fight (where I did take a lot of damage).
- Wingbeat also doesn't require 40% light blue/green, I've seen it happen as low as 23%.
- Vampirism causes dark blue opening.
- At the start of the battle, the bat does seem to only spam Fell Scratch.
Please share your observations and thoughts. I'm thinking we may be fundamentally misunderstanding the combat behavior of bats; perhaps they start using certain moves after taking certain amounts of damage or something, rather than it being based on openings?
EDIT: For reference, I can fight bats comfortably at 21 AGI, 15 UA with 15 STR now so with those stats you won't have problems. But it does bother me that they don't behave as the wiki describes them.
EDIT2: Added cause of dark blue opening.
