Weighting ilevel calculations

[StouterTaru]

13 only if equipping a shield otherwise it's 1 Wep, 5 Main Armor, 1 Belt, and 5 accessories for 12. For tin can or robes you divide by 11. They do not get counted twice.

Equip a 2-handed weapon (level 13 or higher) and nothing else. Use your method to figure out what it should call your ilvl, then use mine. You are wrong.
