Two mages are better than one.
Communion is an arcane technique that allows one mage to draw from other (however it is ensured) willing spellcasters to bolster their own prowess and weave spells greater than any one mortal could ever hope to achieve. Such unions were once under the scrutiny of various gods of magic, fearful of what an ambitious wizard might obtain with it, but with the
End of All Things, all such constraints have fallen away. Now, it is only wizards inability to get along that stop Communions from being more common.
Effect
The Communion consists of two spells: Links and Anchors. Each member who wishes to be part of a Communion must know the Link spell, but only one needs to know the Anchor.
Anchors
Anchors are the leader of the Communion, the one who draws power from the others and initiates the communion.
Links
Links connect themselves to the Anchor and allow her to draw power from them, and once connected have no choice.
With a Communion, a wizard can affect any facet of a spell. At the least, they can cast it as if their magical might was greater than it would be individually, with the magnitude of such an enhancement proportional to the Links in the Communion. The most skilled the Anchor is, the greater her control is over the power she commands, and she becomes able to create effects that reduce castles to rubble or darken the skies with metal hail.
Magnitude
The most simple use of Communion is to enhance the sheer power of the spell, often well beyond its normal limits.
Reach
Similar to Magnitude, Communion Anchors can increase the regular reach of a spell from yards to miles.
Area
Area-of-effect spells can be widened until they bloat across entire battlefield, or even kingdomds if enough Links are called.
Depending on the exact nature of the spell, other, more esoteric elements can be increased if the Anchor is knowledgable and skillful enough.
Ooo this is a really interesting idea. I can see how it could easily be abused once the Link has cast the spell to chain them to the Anchor. Someone who can talk a good talk could easily manipulate people into agreeing.
Yeah; and once you're there, you are on the hook. Some might make a break for it and run when they realize what's going on... If they aren't already too drained to do it.
