Soyweiser, items such as the banner, copper plate, etc cast turn0 spells, therefore they won't work in a reverse communion unless the entire communion is brought together with crystal and slave matrixes. even than it's about a 50/50 chance of said turn0 spells to work due to the spell order in which they take place, if the communion slave+master happens before LotNS of the banner/crystal shield than it will benefit the reverse communion, if not than it won't.

he can still use reverse communions, just without items. useful buffs would include PotS(if using astral battle magic in the reverse communion), summon earthpower(both earth spells and reinvig, so always useful), body ethereal+personal luck(slaves' survivability), etc.
