A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.
From here.
The discarding of the ring from your hand is part of the trait for rings and not it's ability. So the "If the card discards itself from the hand as part of its ability, this discard is done from the resolution area." part of the comprehensive rules doesn't apply.
