Let’s come up with some new spells.

I came up with a new spell, and it's a super spell: Catalistorm (a combination of the words "Catalyst" and "Storm"). The idea is this: extremely powerful catalytic rays strike all enemy creatures. They kill creatures as a percentage, and if you get 30 points of "Magic," you can instantly win the battle because they will kill all enemy units. Strangely, this spell doesn't affect creatures that are immune to magic.

Characteristics:

Chaos Magic
6th level
Mana: 200+10 for each point of "Magic," after 30 points, the cost will no longer increase
Percentage of kills: 25%+2.6% for each point of "Magic," after 30 points, the damage will no longer increase.
