Wizard's Test wrote:Spell. Wizard only, and only if a character in his company has a Gold Ring. Play to test a Gold Ring; make two rolls (or draw two #'s) and choose one result to use for the test. Wizard makes a corruption check modified by -1.

A wizard is bearing a gold ring item. He plays Wizard test on the ring item he's bearing, then he plays a ring special item playable according with the test's result.
What's the amount of corruption points he has to roll against, when it comes to the corruption check? The corruption points given by the tested gold ring item, or the corruption points given by the ring special item played?

I think it's the latter, because "normal" ring item has the keyword "immediately".

If tested, make a roll (or draw a #) to determine which ring card may be immediately played

The test happens before the cc so you have to make the check with the new ring and whatever corruption points that give you.
