So you want someone to log in your character to train your Niss for you? Hope you have all these jelly in your inventory or bank ready in case of that.

i know you're a water (been a while so not 100% sure but i know you have a team...) so how are you unable to train her?

If you need tips on training then anyone will be glad to help. there is a link in my siggy that should also help (you can auto or find a spot to sit if you don't feel like autoing). if you do not find it useful then you can use search and find others. if you have an earth with emote then you can also have them wall niss and take her to higher areas to test your luck.

when niss is 20 do the pet lethe quests (there is 14 known in game) and scroll her to con and int. enough con so she is able to survive.
