So I have a ninja wanting "Ring of Telekinesis":http://www.dandwiki.com/wiki/SRD:Ring_of_Telekinesis. No special information, just functions as if one cast Telekinesis.
Here is "Telekinesis":http://www.dandwiki.com/wiki/SRD:Telekinesis
My issue with it is anything that has a check like grappling, disarming, etc says...
"...you use your Intelligence modifier (if a wizard) or Charisma modifier (if a sorcerer) in place of your Strength or Dexterity modifier..."
So with this I can see 4 possible solutions, I just don't know which one would be closest to the rules.
1. The stats are based on the caster that casted the spell to make the ring.
2. The character using the ring picks between the two stats, whichever is higher.
3. The character uses the stat based on who made the ring. i.e. if it was a wizard the ninja would use his Int.
4. This item can't be used by anyone other than someone who has this spell in their spell list.
