.....The builds benefitting from this the most however would probably again be physical though, since if putting say a water rune makes hydro affect physical weapon damage then warfare/hydro would be pretty viable and boosting hydro would be more efficient than boosting crits....You only need 1 physical rune though. The remaining 2 can be elemental.
Yeah but the damage will be very uneven.Also I would like to point out that spears are still a thing in this game. With points spread between int and fin, the hydro/warfare companion/avatar could jugle between a very exotic arsenal of wands,staves,spears,bows and crossbows....and I think we just made Finesse Cleric a thing now for mixed damage parties and full physical parties.
Geo/Warfare on a full undead party could also be a hilarious setup provided you are not fighting undead or voidwoken which are immune to the spells covered by Geomancy,because Geomancy covers 2 elements (oil and poison)
That being said though, I guess you could pick up a Crossbow as a Pyromancer and just use fire arrows all day long when your spells are on cool down or use it in lieu of a staff. Nevermind, the tool tips lie.
Did you do elemental fire arrows using a crossbow with a fire rune in it?
