Can't get communion to work

[llamabeast]

It doesn't matter what order they cast Master/Slave in. They can be all jumbled up in any order, it's not important.

Why do you say it doesn't work? I think that the path bonuses to the master(s) aren't shown, but they do get the benefit.

However, when I cast a self buff, it affects the slaves and the master.

This means it's working. After the master casts the buff, you should find that the master has accrued much less fatigue than expected (though he will always get a certain amount just from his encumbrance), while all the slaves will have gained a bit of fatigue. You should also find that the master is able to cast spells with high path requirements that he wouldn't normally be able to cast.
