been thinking about this a bit.
going the multiple 'jack angle control at a distance
keep in mind i dont do hard crunch for items in my own games.
just kinda wing it
but control crystals
material components Diamonds
Feats needed IK Craft wondrous item
spells needed Mending, Telepathy, Message, Tongues
DS spells also needed Electric Scry, Instant Reboot, Power Down
DV 20 for the Craft Wondrous Item to prepare the diamonds.
There is the central crystal for the warcaster, as many as wanter for the 'jack crystals
maximum 'jacks are = to the warcaster level
range is line of sight extending the control and focus range.
what do you think, odds are too powerful for too little.
