After realizing that even with the Single Companion Rule Change i made to prevent combat scenarios from becoming too long and boring, there are still many other ways to overcrowd the party legally with the D&D 3.5 rules.
Thus i felt no choice but to expand the limit to the Magically Bound Followers, which are among other:
– Undead, Animated Objects, Summons, and Dominated followers.
A group that is obviously missing are voluntary followers, which are counted among the Leadership feat. Followers need to be sentient and willing to be part of the Leader’s team, but can also be deterred by actions of the adventurers that are in direct opposition to the followers alignment.
As it stands now, all Magically Bound followers will share a pool of a maximum HD, being 2x Casterlevel.
