Wand of Dowsing to Divine Intervention

[Gridxd]

So this is a really shady scenario and I need a good reason why this would/wouldnt happen.

A level 9 cleric uses Wand of Dowsing then Searches for Divine Intervention. While he's searching, I use steal a level putting him to level 8. Before finding Divine Intervention, he simply sells all his armor for a level (its during his turn) putting him back to level 9. He then claims victory. Does that make sense? His logic is that its his turn and if I can interrupt his dowsing search with steal a level he can sell. Would Dowsing have to resolve first or is her right?

And loud arguments definitely did not solve this one.
