[Lonestar]

The following skills could do with being affected with prolong and it would make them actually usable:
- Brine blade
- Ensui Veil (these two just make sense considering ring of pearls works)
- Quickness
- Invigoration

Maybe brighten but it's already a decent skill.

Quickness and Invigoration are already affected by Prolong.
I don't know why Brighten isn't either, but it is what it is. Though I'd be careful with giving certain buffs the 'enchant' type as it could easily go out of control for a miserable 3M cost.
