Just wondering about whether or not it would be possible to get Diamond shaped aura's on top of the Circle and Square shapes.
Square(X being aura center, O being where the aura reaches)
[O][O][O][O][O]
[O][O][O][O][O]
[O][O][X][O][O]

[O][O][O][O][O]
Diamond(E being where Aura doesn't reach)
[E][E][O][E][E]
[E][O][O][O][E]
[O][O][X][O][O]
