Macros

Macros are meant for the more advanced users, since you'd need to use "*unit" (short for the UnitID of the enemy) for a macro to work. To cast Polymorph on the enemy and print out the name of the enemy in the party chat you would have to do:

/cast [target=*unit] Polymorph

/script SendChatMessage(UnitName("*unit"), "PARTY")

FAQ
Will you ever have Gladius function in a non-arena environment?

- No, Gladius is meant for arenas only and it'll stay that way.

Can I hide that annoying header ("Gladius - drag to move")?

- Yes, simply lock the Gladius frame.
