BTW,I see that energycost now updated new format which is
--------------------------
energycost {amount} {mponly} {disable}
{amount} - Unchanged.
{mponly} - Replaces mponly command (left in for backward compatibility).
{disable} - Disables the special based on entity type.
0 (default) = None.
>0 = Entity type (by constant).
-1 = All.
-2 = Enemies & NPCs.
-3 = Players & NPCs.
-4 = Players & Enemies.
----------------------------------
from 2768.
So I recommend you the new format...
What? But I.. I just finished fixing all those...
