This is amazing!

[UlyssesSockdrawer]

Will this also check if the unit attempting to flee has at least one MP remaining to complete the move 'offboard'?

[kuronekochomusuke]

no, it just checks if you can make it to the edge of the board.

[HammerGS]

Let me know if this is ready to go?

[kuronekochomusuke]

yea, it is ready now

[HammerGS]

Limited testing and seems to work.
