When 2 or more sorcerers in a group cast the same high level skills, they sync up. What exactly does this effect do? Does it increase the length or damage of the spell? Double it? Decrease casting time?
What actually happens is, your pawn mimics your spell and joins at the very charge your spell is at. So if the full charge time is 20 seconds and you've been at it for 15, the pawn only charges the remaining 5. This also works vice versa if you mimic a pawns' spell.
Both spells end up being cast. There is no change to the individual spell, except there's more of it.
