The abiliy to let a chosen magic user to tap into your stores of magical power. The person you wish to get mana from must be in your group.

syntax <syphon jigogran>
(jigograns screen) Dreadnaught is attempting to syphon your magical energy {type accept to allow} <accept>
(dreadnaughts screen) You will now be able to use a portion of Jigograns mana.

Or something along those lines at least. Just an idea. Tell me how stuipid you think it is,or if you thinkg it is good.
Any feedback will do.

There used to be a spell called channel that did exactly what you are saying. I wouldn't be against having this skill back in the game.

I also would like to see a willing party member be able to have his/her friends use the arcane to drain mana.
