The Good, the Bad, and The Ugly: Spells

[Tuna-Fish]

iirc, for missiles precision is only used to determine the square that will be hit, and the chance to hit someone in that square is 10+2d6* vs 10+shield defence+2d6*, tried against everyone in the square until it hits or runs out of targets, possibly in an order of size.

Observation to be made is that targets with v.high shield defence, ie nataraja with 2 weightless tower, are practically immune to missiles.
