Some that have to do with water. Perhaps a Create Water spell at will at low level. Then, perhaps Cone of Cold and Wall of Ice at a later level.
I think you might end up liking some of the spells Im making myself, Im sending em over when theyre done. Got quite a few thats inspired by you and Mr. Muffin (when he goes on a Mirc rampage).-
Clay: Yes I have seen the files, they where quite interresting, but I think the Iouns cost to little, I suggest you increase their cost by a factor of 1,5. On a lighter note, I really liked the beetle not to mention that the grafts where excellent.
Cool note on the Iouns. Do you think that even the ones that grant a bonus to saves vs. Poison & Disease are too low in cost? I was taking into consideration their limited appliance when evaluating the cost.
The beetle was originally intended as a "joke" when I first thought of it, but after some thought, I thought it might work though. Could be dropped from the sky too, Bag of Holding + Flying Carpet
Find any mechanics errors? Misdemeanors?
On another Lighter Note, I think Chameleon power sounds cool. What about giving it the ability to alter its own size at later ages? And how about giving it the ability to use a powerful Entangle?
The cameleon power could give it cover while flying...Making the creature difficult to spot, since it will blend with the sky. this ability could improve its chances of surprise, from the air! Mmmm ariel death machine.....
A prehensile tail would e interesting and unique amongst dragonkind too. It would allow for an extra grab or improved grab attack.
