no it doesn't seems to disappear even after the points for training are over... is there a way to turn the training off or something?It has been fully trained, so the option is gone. I just checked and the abilities do show on tamed untrained pets. I think they look great.
Easiest way to get something similar is to train a pet on TC using a training gate in New Haven, but you'd need to tame it ofc. Or, if you'd like I can give you a bunch of trained pets on TC if we can arrange time. I think that would save you some time.
