For the mage skill, u can max out all the blink, evasion, aerial evasion, counter spell and HP passive for survivability.
Poison lvl 1. The growth is no good until from lvl 1 to lvl 10. It is because only when lvl 12 it becomes 3 spots and its coeffiecient increases from 1 to 1.5.
Shockwave lvl1. Learn for disable purpose. The growth is no good.
Force Explosion lvl1. Good for AOE killing. The growth is no good.
Glacial Spike. Max it. You get extra hit when the target is large. Higher lvl glacial spike has higher freeze rate also. Moreover, it can be boosted by your % water.
For Fire tree, you can learn down to flameroad and ignition.
I am not sure whether your shield has been revamped to aura type or not. If so, do not learn ice shield because you can only activate either fire aura or ice aura. If not, you can choose to learn both shield and you can also learn chilling mist.
If the frozen state has been improved until u cant break the ice within the duration, then you can max out glacial wave. If not, leave it at lvl 1 for disable purpose.
You can also learn both flame spark and frost wind to have more skills to spam.
If you have extra SPs, you can choose to max out skills like flame spark and fire bird which have great growth.
