Communion - items of master affect slaves ?

[PvK]

You can have multiple communion masters, too, huh? Buff-o-rama...

Changing a little the subjet. If I have two comm masters will I need twice many slaves to rise magic paths of those two or I will need the same amount like having only one?

[Ironhawk]

Same amount. All masters benefit from the same from having slaves. The only difference is that more masters means the slaves overload on fatigue faster since there are more people pouring fatigue into them.
