Seeking X-Zone information

Does anyone here know how the X-Zone spell works, the reason I'm asking is because I'm planning on moving the X-Zone spell over the Aqua Rake Lore ability. I still want X-Zone to have the same effect as it originally did under the Lore ability. In the Bank C3 documents, I've only found these:

C3/2846: C912     CMP #$12       (is this X-Zone?)
C3/2848: F01F     BEQ $2869      (branch if so)

C3/5151: C912     CMP #$12
C3/5153: F019     BEQ $516E      (branch if spell is X-Zone)

12 is X-Zone's current spell ID while 8E is Aqua Rake's ID. Are these the only things I need to change?
