Magic items in PFS with multiple properties

[Mordenheim Fleetwood Mac]

For instance, can you add +2 charisma to a phylactery of channel positive energy RAW? Would it be legal in PFS core, if so? The implication under magic items on SRD is that you can. Organized Play guide seems ambivalent...

At the top of the PFS forum there's a stickied "How to upgrade your gear in PFS" thread with answers to questions like this.

Short answer is "no, custom items are not allowed in PFS".

There are a few exceptions, outlined in that thread.

Only those items which are designed to be modular in enchantment can have multiple properties. Items such as weapons and armors.
