Kind of stumbled across this while messing around with a criminal character...

In Glitterstone, Ynystere, if you stand on the side of the fence opposite the community center and above the public farm, you are able to attack anyone that is not near the stairs leading to the guards with impunity. This is because the nearest guard (north side?) appears to only be capable of melee and cannot perform attacks though the fencing and his buddy (the south guard who knows magic) does not get triggered at that distance.
It's an easy enough exploit to get around, assuming the target can get to the stairs, as the South Guard lobs fire and ice at the attacker immediately and with ease. It also does not prevent the target from attacking in retaliation.

Just wanted to identify it, as I did not see mention of it.
