The Hidden Forest

On UF-Client, i can perma use the disc Fortitude.

Disc shows up and is useable again when disc runs out, even if i interrupt the disc manually.

So I looked into it a bit...

There are two "fortitude" discipline for Warriors.

1) Fortitude Discipline available at level 59 that gives you 12s of Melee Avoidance - 40 Minute reuse.
2) Fortitude available at level 60 that increases AC by 59 for 12s - Instant reuse.


So you should be able to use Fortitude as much as you desire.
