Barrier + Water over the enemies head = drowning
its even more effective against mages/magic users where chanting is required to successfully cast the magic to dispel the water/barrier.
And this is merely a 2 simple spell combo. Imagine adding even more simple spell effects like "ink" and "poison" and "paralyse" into that combo, the enemy is blinded, poisoned and probably paralysed too. What a crazy but logical use of combination magic
