I would rather spells just combo into one another rather than rely on a debuff that the enemy might be immune to or has had diminishing returns. I also don't like the Ram Voice > Dragon Voice cause it forces you to be right next to the mob then run away from the mob. You can't use petrification > drill cannons on bosses. You can do the Dropsy > High Voltage but it only increases your potency to like... 200... which I guess is still better than 130. I just think they need to make the spell combos more worth while, more of them, and less reliant on status effects. Also I don't see a reason for the Final Bosses to be immune to your spells if you can't only go in premades.
