Induced by the RoBF discussion.
Why do we have both name types of items, with properties spread across both? What's the difference between a Tattoo and a Rune? None? Maybe there should be. ;)
In keeping witht thier origins, why don't we make these changes;
'Tattoos' are familiar creating items. So the JKF, FF, IF, SF and Hal all come from the relevant Tattoos.
'Runes' enhance the minion they are engraved on. The ToA become a Rune of Augmentation. Same as the ToE.
If we really need the current auras, I'd suggest a seperate type of 'tattoo' entirely, maybe called them 'Wards'. These would provide nothing specific to the minion wearing the Ward (maybe even get rid of the Armour/Power Shiled restriction), but instead they provide a team wide aura effect.
You would still only be able to use one of these on the same team at any one time. ;)
