AST QoL Changes

[Dyvid]

I know, I know. There are a ton of AST threads but wanted to focus mainly on small QoL changes that wouldn't change the overall gameplay of the job, just minor buffs to certain abilities. Most are inline with the buffer aspect of the job.

*Lv.46 Gravity - add a 10s slow effect
Lv.52 Combust II - Make this AoE similar to Aero III

*Collective Unconscious - Restore 10% of the AST mana

*The Spear - I love the concept of this card but it needs to work on action already on cooldown. If you can't fix this problem then maybe the card needs to be changed.
