Magic raising skill question

Quick question: do skills that say they do stuff like lower the mana cost of a spell, or increase the crit dmg of a spell... do those apply to ALL class abilities (i.e. non weapon based ones, the ones in a class tree.. like stone fist, fiery grip, assasins blade, piercing javelen, ect)? Or just to 'magic' ones, like sorcerer spells?

All class skills, from what I have seen.

cool even the ones that aren't magic like at all, like assasins blade and stuff?

You will notice that even assassin's blades uses magicka.

All class skills use magicka. This is a form of balancing, as blocking/dodge rolling require stamina, so they likely have to go a bit more on the magicka side of things to keep it balanced between magicka/stamina usage.

As for passives that say they do stuff to your skills, it all depends on which skill tree you're pulling the passive from. Your racial and armor skill lines will affect all of your skills across the board, other skill lines usually have conditions that go with them like "This will only work with such and such weapon equipped" or "This will only work while using skills from the Siphoning skill line".
