I think it synergizes well…
Transpose for huge con then turn into a giant with 100k health?
Swell buffs+rune of ice = 3x benefit from the buffs?
IDK just some thoughts I had.
Other than the cast times, why dont you suggest it? Another thing i was thinking is use ice pillar and id be able to cast those 8 second spells… not if the mobs dont stop though.
