I'm struggling here to understand what the big issue about using 2-man rituals is.
There are 4 two man rituals that are of any use in a fight. If these 4 rituals are the difference between you living or dying in a fight, then I say you need to learn new attacks bigtime.
I mean, one sends you to the pool of life when you die. hardly an offensive ritual. One creates an alkar around the mage. Come on. its called timing.
One allows you to use charming within an area instead of a location. You know the defence to this. And the last gives you a few diseases. Now compare that to the Demon lords, or a bards entourage as Meerkat said.
As I said if you die because of that small advantage then perhaps you need to evaluate your methods of attack. Its only teaming if the other mage is there and starts casting charming spells at you through the Mag rit.
Feel free to reply with a barrage of abuse and filth Kes. I'm used to it from you. If however you have a sane and interesting answer then that would be a welcome change.
