As we all know, there are enemies who are resistant, very resistant, or outright immune to various damage types. That's a good reason to avoid playing a build that relies exclusively on a single "color" of damage.

However... there are also plenty of enemies with multiple resistances. Slimes, for example, starting as early as the Baby Slimes in the sewer's dinosaur wing, are very resistant to crushing, and very resistant to psychic.

What is the intended strategy for an unarmed/psychology character to interact with enemies like this (ideally, besides the obvious answer of "don't play that")? At vaguely appropriate levels, there's just no real way to injure them at all with this combat set.
