Earlier this day when I was playing the Never Ending Infinite Game, I came up with the idea of spells, most of the spells I came up with can currently only be feasibly used in Never Ending Infinite, but anyhow here they are:
Freeze Potion:
Cost=10, Ability: Freeze all pieces in a 2x2 square for 1 move, can only be placed in a 5 block radius around a friendly piece, only affects enemy pieces
Wall:
Cost=6, Creates a temporary wall that is 5 squares long it lasts 5 turns and must be placed directly around a piece, only one wall can be placed at a time (a wall can be made transparent and can be leapt and flown over.
Transparency Potion:
Cost=5, can be thrown in a ten block radius around a friendly piece, affects a 3x3 square and can be used on walls, last for 2 moves.
Leaping Elixer:
Cost=5, can be thrown on friendly pieces giving them the ability to move the way they move but also leap over pieces and the move like a knight at the same time, last for 3 turns. (I need better rules for this)
Undead Army Summoner
Cost=15, summons a band of guards and knight in a 6x6 radius around friendly pieces. the summoned pieces last only for 2 turns, and one of them can simultaneously be moved with your own pieces. If they are touching other pieces then their position may change. (need lots of help with this one)
The Costs are costs in infinite never ending
