Battle Grid

The battle grid, also known as the playfield, is a rectangle composed of 4x8 tiles, used for combat. Beings that can move are normally constrained within this rectangle and cannot move out of it. Additionally, beings can only move within one half of the square, without mechanics that let them occupy other tiles. Blue tiles are usually occupied by the player and red tiles are usually occupied by enemies.
