Allied delvers can only target ENEMIES with Angler Light. They cannot heal themselves or allies.

[Ranylyn]

They also cannot dive. Assuming the same goes for Sandsharks.

I'm assuming this is only with Total Control? And define 'can't dive'.

[Ranylyn]

Untested without total control. I'll get back you you on that.

Dive gives them a + Shaped area to select from. Nothing inside it appears to be targeteable, including themselves. Untested against enemies (it'd be freaking hilarious if they could make any enemy dive, I need to test that.)

[Neus]

There's probably quite a few monster skills that behave this way so I'm expecting more reports. Please let me know if it's exclusive to total control or not (I assume it is but don't want to dive in to try and fix it without verification).
