Beast Tamer Guide ?

All skills need 1 point to unlock the next.

I think they required a fixed points to unlock, not 1 point to unlock next skill?
E.g:

Majestic Trumpet: Level Required: 14: Required Bear Skill Points: 7: At Master Level: MP Cost: 35, Damage: 210%, Max Enemies Hit: 10, Duration: 15 sec. Master Level: 20

In other words, sometimes I have to use some SP to satisfy conditions to unlock next skills, not just only one point.
