[solved] How do i change size of special attack

no, it's just a typo.
what he meant is "zwidth". You can imagine it the following way:
Assuming you have a book that you (for whatever reason) want to measure. Let's say, its width is 15 units, it's height 25 units and its depth 5. Now, in DC terms, it'd have "w: 15 h: 25 zwidth: 5". x/y tell you the starting points.
