I think Graal could have a system in which each player has his/her own special move that they could use in combat or in quests. This move would be activated using some other button than the orignal three, maybe the F key or somefink like that. Anyway, anytime during the game, each player would be able to choose their special move from a list, or they could make their own. They'd only get one chance to choose, and the special moves would have to be balanced. As in, no super duper blast thing that kills everyone in one hit (Although Elven Lands would probably be drooling over somefink like that

)
Here's how you'd make your own move:
Graal could have an external program like Graal Shop where you start off with bomy or a human in a viewer window. If other races are uploaded, you'd get the chance to view that race as well. Anyway, each "limb" of the race would be a seperate sprite, and the sprites wouldn't be derived from sprites1.png (Instead, they'd be built in with the program). Also, there'd be a frame-slider on the bottom of the screen like Graal shop.
In the program, you'd be able to rotate and move around the limbs in each frame. The program could also have special hidden sprites that are visible in the program, but not in the game. These sprites would be the ones that hurt the other player, or trigger the switch, or unlock the door, etc. Once you place a special sprite, a menu would pop up, and you'd be able to set the sprite's function.
Another feature would allow you to import sprites (Like Graal Shop ), for beams, blasts, and what not. And after the entire move animation is done, you'd be able to set the move's attributes (i.e. the power of the special sprites that hurt the other players, the speed of the move, and anything else that would make it more fair or more effective in the game).
When the entire thing is done, it would be cool if you could send it in via an autosubmitter on the G2k1 website. If the move seems balanced, you'd be able to use it in the game!
Maybe creating such a program would only require modifying Graal Shop, but either way it would be awesome. No NPC skill needed to create a special move, only creativity. Having special moves in Graal would vary players' fighting tactics, as well as adding on to the customizable aspect of the game. Each player could have a special move that compliments their fighting style.
