Thanks

(this game, I am playing as G.A. Arco)

Simplies solution. Get death mages and maximize death gems production. Pale riders led by several Bane Lords are gonna do the job most efficiently and painfully for enemies.
Pale riders single casting gives you 20 riders for only 10 gems. Bane Lords cost 10 gems IIRC. So, its relatively cheap underwater killer army. You will need to give some water breathing items to your BL's but playing Arco that shouldn't be a problem.
