In Barbarians of Lemuria, the Arcane Power [AP] cost of a spell can be reduced by adding requirements, such as a special item, line of sight, or obvious technique. On page 49 we have:
Obvious Technique: The caster must gesture, chant, dance or make strange sounds during the brief casting process.
Since there is an "or" in there, a spell could have an obvious technique of a gesture without a "magic word", or a magic word with no gesture.
If the spell has a gesture and a magic word, are those two obvious techniques, or two parts of the same? If they are two obvious techniques, are you allowed two of the same requirement type to reduce spell AP?
By way of example:
Methyn Sarr knows that Krongar is in the palace, and will certainly want revenge on her. In the grand hall there is a huge chandelier secured by rope tied off to the wall. She will trick Krongar into stopping under the chandelier and use a spell she devised to untie the rope. This is ruled as more complicated than a cantrip, so is a spell of the first magnitude. When casting the spell, Methyn points her ring and index finger at the rope and says "Shazam!"
Does the spell cost Methyn 4 AP for obvious technique, or 3 for two obvious techniques (the hand gesture and the magic word)?
