Selecting Equipped Effect via Script

[Diana]

One npc has the Helm of Brilliance. He can cast either Fireball, Prismatic Spray, or Sunray while equipped.

 

The question is how can I select which of the 3 is cast via script? I've looked at the GB-CLER.BS and GB-FIGH.BS for clues but most of the items shown can only do one thing. I note that coding there is coding for Blessed Bracers which has two effects, but I don't understand this Player1Fill stuff as shown below.

 

UseItem("Brac23",Player1Fill) // ~Blessed Bracers~

 

Thanks.

In theory you should be able to use

 

SelectWeaponAbility(I:WeaponNum*Slots,I:AbilityNum*)

 

But I don't recall anyone ever getting more than one ability to work via this method.
