For example, with an IP 50, the multiplier is 2.5x, the intelligence skill raises this to a multiplier of 3x. Counts separately for each pet." (from another great page:) http://doomlord.wikia.com/wiki/Pets
Skillpoints maximum: pet's baselevel + itembonus but skill can't more than pet's baselevel/2. For example if your pet's baselevel is 80 and have +20 from an item, the sum of skillpoints is 100, but one skill can be only 40.
That page - not so great. Has lower lvl items (for instance, the other page has rings and nekclaces up to lvl 80, this page has only 55)
Also, I know the description of Intelligent skill, I can read it in game. It doesn't answer my question though - does one point increase multiplier to 3x, or when skill is maxed?
