This calculator is intended to help referees calculate damage for battles in the TCoD ASB League. It is based upon my own reffing scale, more information about which can be found in my Energy and Damage Guide. The damage percentage given is only the base amount, without any item bonuses/terrain bonuses/what have you included.
Note also that the calculator only works for damaging attacks. To determine damage/energy costs for other kinds of attacks, refer to the full guide.
