I don't know too much about the AI doing stuff like that in AOK, but the trigger system is meant to works well for that. If it's a tribute you're after, then just write a trigger like this:
Trigger 1 - Tribute on command
_Cond: anything (timer, object selected, etc.)
_Eff: Tribute - stone - from player X (or Gaia if it doesn't matter), to player 1 (or whoever)Does that make sense?
