| yeah, nice as always stalker. Copy pasted. I think the criticism of the idea is quite constructive too. Going to let it all simmer and see how I can refine something down for my group.
I agree about the energy change through the arcana skill. Maybe it could be used to lower the creatures resistence to that energy type instead of changing the energy type (the resistence is the reason why a wizard would want to change energy type I imagine). Something like this: Arcana: Magic Sense: (Move Action; vs Enemies Fort Defense) Honing your magic sense to the flows and ebbs of the magical defense that surrounds your enemy, you fire your next spell at your enemy at the precise moment it reaches its weak point. Lower one type of your enemies resistence by 5. If you beat Fort by 10 or more you can lower 2 types of resistence.
Don`t think you should be able to do this against Martial Monsters.
Maybe arcana could be used as a daily power to recharge a magic item...
Another thought that occured to me as I read the list, the Streetwise skill was brilliant, and its a skill I would like to have more uses for. An Ignore Terrain in an Urban Setting would be a cool one too, someone used to bar brawls, sliding over bars and tables, or leaping over trash and homeless hovels in back alleys, like the Nature skill you invented.
I think I will limit the uses to encounter stunt and daily stunt as per alex's suggestion and do away with worring about keeping track of the cumulative usage penalty (which if you use it maybe could increase to -10 at paragon tier and -15 at heroic to limit the amount stunts are used at high levels... just a thought). And the idea intelligence influencing the amount of uses you get per encounter also tickles my fancy, though I think one daily will be the limit for me. I guess the flip side to that is the most intelligent characters i.e Wizard and Warlock arent really going to be spamming 'leaping charge' 6 times per combat so thats ok.
I'm going to take a careful look at which stunts Im going to make daily and which ones can be encounters; if I allow Intelligence as a usage modifier, I think I will limit each stunt to once per encounter regardless.
Anyway, my brains alive with ideas which means that the ideas you've had are great! Thanks! |
