So these two groups look like they are complements, same thing as Manabolt/Stunbolt trees being complements. The only difference should be that one does Stun Damage, the other does Physical damage. These two groups are also complements of eachother, since one group is Mana Spells, the other are Physical spells.
So Punch and Shatter trees are physical spells. But for some reason, Punch is Indirect, but Shatter is Direct.
....Why? Shouldn't Shatter/Powerbolt/Powerball also be Indirect?
Also, how exactly does an indirect touch spell work? Unarmed Attack vs. Reaction + Intuition to touch, then Spellcasting + Magic vs. Reaction + Intuition for the spell? That seems weird that they could dodge twice.
