Here are two possible flags to add to specific item families:
Sword Family Flag 3: Apply Quick Sword Rule
In other words, some swords have the effect of the quick sword rule while others don't. In theroy, this could replace the Quick Sword Quest RUle.
Candle Family Flag 2: Z3 Candle
If 0, the candle behaves normally. If 1, then the candle creates a flame in front of Link that doesn't move, just like the lantern in LTTP. This must be possible, since there was a bug that caused Z3 styled-candles in an earlier beta. It isn't reasonable to use a Misc value for flame distance, since candle flames shouldn't be a long-range weapon. Or should they?
