Undead Companions

[Gabe PC]

I am running a PC in PFS who is an Undead Lord, and just reached level 2 with him.

However, this brought up a new issue, one I am fairly unfamiliar with:

Finding a creature with 2 HD to make his Undead Companion.

Right now, depending on how something works, I am thinking about a Wolf, as it is 2 HD, but it depends on whether it retains the trip abilty part of its bite attack. The Skeleton template is a bit confusing on that.

If it doesn't, I would need to consider something else at 2 HD, and I still need some advice (why I am here) for higher HD creatures to make into Undead Companions as my PC levels up.

Yes, a wolf skeleton retains trip. Not well-versed on creatures to make into undead companions, sorry.

I have always assumed that the companion can gain hit dice as the cleric gains levels. Thus, a human warrior skeleton can become 2 HD.
