Game Mechanics: Low level mobs double attacking

[Torven]

Incidentally Mackal decompiled the client and discovered that double attack chance is rolled against 500, like so:

if level <= 35: chance = skill / 500
else: chance = (skill + level) / 500

For monks or client monks at least, it seems that level added to the skill starts at 30 instead of 36. I couldn't prove if that applied to all client classes or just monks as I didn't have clean enough logs of that level range. I just happened to have good monk logs at that level.

For NPCs, Skill = level * 5 up to a cap of 210 until level 51. Level 51+ NPCs have 250 skill.
