Attacking merchants
 

What determines whether a specific merchant can be attacked? Is it a certain field in a table, or hardcoded somewhere? I have noticed that I can attack merchants in Shadow Haven, Crescent Reach or the tutorial "B" zone (mines of Gloomingdeep), but not in North Qeynos or West Freeport. [Edit: clarifying that Freeport is the old zone, and this is specifically merchants - I can attack regular mobs and guards just fine in those zones]

The `special_abilities`column in `npc_types` causes this.

Got it. Tried this on Ping in Freeport and was promptly flattened, as desired. Thanx!
