What do you think about anti-bot monsters?

Do they have elements? Are there any affected by heal?

Only lich is undead, but does it really matter whether they have elements or not? They only appear one at a time.

You guys should just check the page on strategywiki about bot-catching monsters. It explains in general what they do and in detail how to get rid of each one.
