The Skill that is supposed to allow you to teleport your parents to you doesn't work at all. It only functions when you are standing on screen of your parents, and why the heck would you need the skill if you are right there?
It's also hard to determine if the skill to save your parents xp works since there is really no indication of it's success except for the stun noise and it making one, (but not both) of the parents stand up. It usually effects the father.
By the way, the NPC did say it could teleport your parents to you (when you are in trouble) but I attempted to teleport my parents to me when my hps were in the red and nothing happend, so yeah, no.
Also on my previous server this skill would teleport your parents to you exactly like the marriage skill, no matter where you are, (so long as it is possible to teleport in the area).
I dont know if it's possible to fix broken skills, but here you go anyway.
