if you plan to join a clan, most of 'em will look for high swords, that'll be the one for train, but in my opinion the best one to train is archery
Well, most clans are looking for high swords, but if you get yourself a sharp 5 axe, and high axes. it's the same as having high swords. If you want to crush their armor, but if you're going straight for the kill, and want their armor, then use swords.
acrobatics! ftw! but out of those 4 i would say swords would be the most helpful getting into clans, however it really depends on what you personally like.
I think that swords are good, especially knockback II sharpness III diamond swords, and a power I bow is good too
