About skill upgrade

I`ll put here a example because I dont know how it is called.

Those things, its like a skill upgrade.
Is there a limit of how many I can choose?
If there is a limit, its based on overall or per circle?
Do I buy it? I saw one topic about that before creating but they didnt said much about it

You can learn it all as long as you have requirement (ex. specific circle or skill lv requirement if have, mostly don’t have though). Can keep upgrading it till it reach max level or as long as you have enough money to pay NPC.

Hmm I see, thanks so much =)
I was thinking I would have to think a build even for my skill upgrades haha
