I don't recall when or how you acquire them, but Ryen has at least 6 magic skills available (not counting debug attack):
- Flameblade - adds fire damage to his sword attacks *
- Darkblade - adds darkness damage to his sword attacks *
- Roar - debuff enemies
- Fire Recovery - self heal
- Combo Attack - AOE attack
- Connection - heal ally based on current relationship value
* note you can't combine flameblade and darkblade together, casting one dispels the other
My Ryen is lvl 45, so you might just not be high enough level, but I don't recall waiting so long to get skills. I think you're missing something.
