improving on a old idea i had i think that sprites should have a passive effect that would make them way more useful in combat.
Drakon would have a rage builder effect so when you hit enemies a small percentage of damage gets added together and when you use a skill like firebolt it would be much more powerful depending on how much you charged up.
seraphynx would have a long charge effect that would revive you upon death and can be used only a certain amount of times.
maskeraith would have permanent statues resistance that would be very useful for knights who have high risk builds and a charge that would remove status effects when activated.
