pretty powerful… and can cause high abuse… I just though of 3-4 ways without hardly trying!!! If no one could have it but me, I’d vote yes, but since that’s not the case… 
Bid: $15M

A high price, but not quite high enough. This is one powerful daemon. Plus there’s nothing to stop Corporations ganging up and doing unearthly damage with Daemons like Ifrit and Iblis. But apart from all that, it’s a possibility.
Bid: $1M.

Waaaaay too powerful even though it’s less effective than intended.  As written, it doesn’t affect any numbers in the subrules of Rule 2.6.  It’s only real use is to greatly increase someone else’s mantenance costs.

ah… yes… not as powerful as intended… I’d love to summon a daemon with -1000 summoning cost {:0)

Chivalrybean:The numbers can only be changed by doubling or halving them.

Ah well, just wanted to see the general response. Ill self kill this after I get more responses and see if I can come up with a better one.

Bucky: Ruleset section 2.6 includes the subrules doesn’t it? 

I am thinking maybe the power can be reduced to 1.5 instead of 2. Ie. divide or multiply by 1.5
