gannon? really? no offence but do you play a lot of Zelda?

Hmmmm.... A simple name would be shades and shines spirit elements. The Shades should be able to poison and/or blind a character (you could play around with the blindness maybe cut the players acc. (accuracy) by half or less( anymore and people will get frustrated) or make it so that you cant see the sign your weaving so memorizing them will be important.plus you could make the two spirits more aggressive than normal ones by that I mean if they get within a certain range they will attack you, maybe only the shines should be the aggressor, because shades have the status effects. The shines I'd say should have high attack, low health, and moderated mana, slow attack speed, and moderate regen speed, plus healing spells that affect other spirits varying in effect dividing the over all power by how many spirits they heal at once this should be considered when a catcher grabs one and uses it as well. The shades should have moderate attack, moderate health, high mana, mod att. Sp., and slow reg. sp.
