Alternate Hirelings and Companions

When it comes to hirelings within the game, it can be boring to have just another mook to carry your equipment, or potnetially betray you. Instead, here is a list of rules to spice up hirelings and how to make them work for the campaign.
Each hireling that a party hires has a list of abilities that they are able to do based on their chosen skill type. Based on that hirelings level, and potentially their class or job, they have a wide assortment of abilities that they offer.
Hirelings have two different abilities. Passive and active. Each hireling automatically starts with a passive ability. At level 4, and each level thereafter, the hirelings will grant additional active OR passive abilities. (Maximum of 6 abilities, including the original passive ability.)
Whenever a hireling chooses, they may choose to select an alternative hireling type for their abilities. Gaining new abilities always starts with the passive, then moving from left to right along that type. Should a hireling be partway through multiple types, they may choose a new type, or to continue on with their current ones. Each type has three abilities to be gained throughout leveling up, with their final ability unlocking at 12th level. After the 12th level hireling ability, a new hireling type must be selected.
