I'd test it myself but I probably won't get to play RD again for at least two weeks.

So:
Does support that boosts hit affect skills? I.e. if Nailah has a support that boosts hit, will Glare also have a higher chance to hit? Or is the chance to hit of skills really only affected by Biorythym?
And as long as I'm asking, does anything besides Biorythym affect hit of skills? (At best, Glare is 33%, worst is 13%, but it doesn't work at all on Jarrod. Why?)
