Spells don't quite interact closely enough to combine with other players, or counter enemies spells. That would be much harder to program, and it would also shift the focus too far from an FPS. This game is primarily an FPS. Thats also why there'll be no pets/summoning spells. This is not an RPG. There are not pets, no RPG style items (but CTF flag - yes, item to steal as objective - yes, but these have no bonuses), no leveling up, no unlocks. This is a FPS.
As mentioned in another thread
, there will be fractals corresponding to the elements being casted. When the spell is complete, the player who made it gets an icon on their hud to show that its ready to fire. Their team mates will see an icon for that spell above their head. Enemies will not know what they have, but may be able to guess if they saw the elements being used.
Spells were originally separated into aggressive and defensive, but we decided it would be less confusing if they were all accessed together.
Spells are grouped by their primary element (the first one you pick). Shields have to match the element they block - fire shield blocks damage from fire ball.
