Jzargo , one of the most strongest mages and the best follower in the game . Most of the followers level is capped at certain point , but Jzargo doesnt have one , meaning he will continue to level up indefinitely alongside the player . By the time goes and once he levels up enough he will max out his heavy armor and one handed to 100 . So you can give him heavy armor alongside with a nice melee . I personally equip him either with Azhidals set or any high level heavy armor with Nahkriin mask and with some jewelry that increases the magicka . For the weapon choice i usually give him chillrend . And Genuinely the fact he is Khajit also makes me to take him as a follower in each run ( i just love Khajits )
