Where can I buy these skills?

Invincible and Endure. Also what level requirement to use them? Thanks

Your class trainer in Elderine has all of your skills past 20th level.
If they are below 20th level, then Skill master Ruby will have them.

Nope, neither of them have it. Not at least from what I see =S
