New item stat...Follow

Maximum number of skill points that can be granted by a % skill increase mod. Currently, you call this attribute "unknown04". As of the latest patch, inspecting an item with a % skill increase mod in game shows the increase as, for example, with the Brewmaster's Mug:

Skill Mod: Brewing 15% (max 45)

You're correct.

Items with % modifiers continually gained in power as skills increased (they scaled indefinitely). So a 10% mod would give you 20 extra points if the cap was 200 and 35 extra points if the cap was 350 and 40 extra points if the cap was 400.

That's one reason that trivials became so high on tradeskill items. They wanted the item to come in the world at a certain rate, but since they had to use 345 as the max skill not 300 since the 15% item was easy to obtain.

Now, it's capped at 45 points bonus no matter what the max skill is.

I wonder if this has set the stage for a raise in the tradeskill cap next expansion.
