If the bomber captures a piece, then it would explode in a 3x3 area (level 2 is a 4x3 area, while level 3 is a 5x5). When the bomber explodes, then the bomber status transfers to another piece of your choice (level 1:pawns, level 2:bishops and knights, level 3: rooks and queens).
ok, i just got chesscraft and want to make a chess varient

i can do something similar, but not the same, hopefully that's ok
 
    
  
  
  ok, how this would work within the restrictions of the game is that i could make a piece called "bomb" that can't move unless another piece is within a 1 square radius (so, it would be like the piece is holding and throwing the bomb) i can't directly make the whole guessing things, but i could make the bomb piece invisible, the exploding thing isn't possible from what i am aware, the closest thing i could do is make it so that if the bomb is taken by an enemy piece, the enemy piece is taken as well and if the bomb takes a piece, it is taken as well, i could hypothetically make the leveling up the bomb thing, but instead of it being triggered by material, there could be hidden promotion spaces throughout the board that would only allow a bomb to access to become the next tier, every tier would allow the bomb to move farther (bomb tier one moves 4 spaces orthogonal, tier 2 moves infinite spaces orthogonal like a rook, and tier 3 moves like a queen, i could probably add some other things to the bomb to make it a stronger piece, if one bomb is taken, i think there could be a way for a pawn to promote into a bomb, again, i do need to add more things to make the bomb stronger (maybe it can't be taken by another piece, the only way it can be removed from the board is if it takes, maybe it can enpassent, ect) i am sorry i had to change the bomb idea so much from the original idea, but this is as close to the original idea as chesscraft will allow, tell me if you have any more ideas (:
 
     
    
chesscraft is an app in which you may create chess variants and pieces, i want to have some fun with it, so comment your variant ideas and i will take my favorites and make a chess variant of them, the URL will be posted in a later forumn
