ZODIAC Final Fantasy RPG

Obviously you have to make an accuracy roll vs. the enemy's evade stat to hit with a normal attack. There isn't a lot stated about techs regarding this in the Core Rules doc, all I can find is that in the Inaccurate secondary effect it says that Magic Attacks and Power Attacks do not require attack rolls to hit. My main question is, what requires an accuracy roll and what doesn't, and do you still make a check to check for a critical on techs that don't require accuracy rolls?

Normal Techs don't have rolls; as a price, they don't crit. However, you CAN take Inaccurate, which as far as I know makes it so you can, in fact, Crit with Techs as long as you're willing to accept a chance at failure.

Negative Status Techs, Attack rolls with weapons, Draw Out abilities and I believe certain Command Skills all have accuracy rolls. Everything else…nope.
