Normalised Item Magic

@Gi Nattak, upon rereading your PM I must admit I'm a bit confused as to what you're asking for exactly. I thought you meant breaking Rods, as Throwing a Rod doesn't cast a spell. However, Throwing a Skean does cast a spell.

Do you want to modify the behaviour of Thrown weapons? Or spells cast by Throwing a Skean/Edge? And are you only interested in Ignore Clear specifically?

EDIT: because if so, what you suggested works fine, I just tested it.

Code:

C2/1895: 80 03   BRA $189A    ;Set Ignore Clear
