Do souls lvl up if Im already lvl 50?, mine don't get exp. I loaded old codes, 1st time I see the vault.

Souls gain the same battle XP that your hero gets unless you're a level25 basic class. So if you're lvl50, you'll need to kill a lvl46+ enemy to get XP for your soul (your soul's level does not matter).
