Here's a little module I've made that calculates the actual gains from stat changes.

It's based on the information found here: http://community.ageofconan.com/wsp/conan/frontend.cgi?func=publish.show&template=content&func_id=2904&table=CONTENT

Usage:
!attribute <attribute name> <value>
Examples:
!attribute int 100
!attribute Wisdom 67
Module code:

Looks good! I'm gonna test it soon...

Happy to hear that.

Let me know if you find any mistakes/miscalculations. I do hope Funcom will update the online reference list if they change the values.

This is great but you missed somthing..

Increases Protection from Electrical/Fire/Cold magic by 0.5 = INT

Same with Wisdom.

Increases Protection from Holy/Unholy magic by 0.5 = WIS

Updated the code with elemental protection. The spiritual protection was already there, though.

Edited the Attribute calculator that Heljeere initially posted and added all the important stats, simplified the command and customized the displayed results.
