I like the addition of 25 spells only for these situations, normally only LB3s can be 25 in power and requirement, but this works fine. It only is unlocked in dire circumstances, which makes up for it being Limit Break in power, but doesn't cost Limit Points.

Entropy inflicts Doom on anyone within the radius but no damage, however they are cured of Doom as soon as they leave the zone. When cast you can cast other spells while it's active.

Everything else is just about okay. Might want something else for Banish Lance. Effectiveness against Divine means effectiveness against Dogmatic origin foes, and there is a very specific power you need to possess for that. The Iconoclasts all possess it, and it's not gained through training or anything. If you want Banish Lance to have that quality, then you can try earning it in-game.

Otherwise, they all look fine.

Would like to note that the number also denotes the size of the attacks too as well as damage, so unlike other RPs that require it to be stated, the size is assumed by the number assigned to the skill.
