Fun times when you could have all mobility spells+buff spells after taking 1 point in every school.. :DD
To be honest, hybrid build in this game probably means you are focusing both str/finesse AND int for spell damage.
If you go mostly for one type, and the other just supplements your char, it probably isnt really hybrid...
For instance, my wayfarer is clear hybrid build - finesse+int+wits+memory make her split thin on attribute points lowering her potential damage/ap, but her versatility is through the roof with all great physical damage and amazing elemental damage from elemental arrowheads+geo+pyro spells. Also best buffer in my party

Well worth lower damage imo
