stoicsentry: There's no commitment + the more, the merrier. :)
iippo: So is there some kind of limitations to these skills and spells :) I wouldnt know what kind of world this is going to be so if you leave the (gigantic...) shapeshifting to just my own intepretation, well Im not sure if anyones going to thank me later.
Dragons are gigantic and breath fire and whatever rrrright and basilisks have this habit of turning things into stone....or no shifting into magical creatures? :<
Sure I could make something more ordinary, if its more simple. Also I am not yet certain about my commitment part - but i would like to give it a shot and see.
The world is high fantasy. We can throw bits & pieces of steampunk into it ala Arcanum, but it's really all up to you guys.
Gigantic would make you, say, twice the size of a normal humanoid, and you might roll to perform tremendous feats of strength, or to topple enemies, etc. Of course that can backfire, as people that see a giant running around stomping things are likely to take notice and devise some plan to deal with the 'problem.' Even still, if you wanted to be 3 times the size of a humanoid, or 4... or 5.. you would be allowed to specify that. Just remember that it has its downsides too... you don't want to get hunted by Giant Slayers!
As far as the shapeshifting goes, it would permit you to assume the form of any kind of being you imagine, but anything you do in that form is still balanced out by your ability to roll. So, you can indeed assume the form of a fire-breathing dragon, but if you can't roll above 100, then your fire-breathing would be no more dangerous than the average character that possessed fire magic. And note that, given the versatility of shape-shifting, it would be necessary to balance the skill out by making it more tiring and energy-consuming than other skills might be, so you might inadvertently be shifted back into your normal body and be given a fierce headache that would make you vulnerable to being attacked.
Sorry for being so wordy, but basically the idea is this: no skill is overpowered per-se, since the DM/judge gets to decide if you're being too ridiculous and knock you down a peg if you get out of line!
Ultimately, the thing about DM-ing/judging is that it's going to make you unpopular at times. People are going to disagree - this is not fair, that's not fair. But, it's like being a garbageman - *someone* has to do it. LOL.
