Ring of the Void "Void • Unique After you resolve your fourth or later non-Kiho action from Strategies in one phase: You may put his card into play from your hand. Open: Bow this card or discard it from your hand: If any player has more cards in his hand than you do, or if you bowed this card, draw a card."
Ring of Water "Water • Unique After you resolve your fourth or later Battle action from cards with different titles in one battle: You may put this card into play from your hand. Battle: Bow this card or discard it from your hand: Move one of your target units home or to a battlefield with one or more enemy units. If the unit moved, straighten it."
If I play my fourth battle action that meets the requirements for both rings, do they enter play simultaneously or in the order I choose? I ask because they are traits, and not reactions, and I'm unclear on the order of entering play under such circumstances.

These cards are put into play by triggered traits, both triggering off the same trigger - "after an action resolves". As described here, you decide which trait triggers first.
