Question

Hey guys, can ANOTHER player trigger the interrupt ability on the attachment “counterspell” from Doctor stranges nemesis set when they play an event while it’s attached to YOUR identity? We understand other players cannot trigger abilities on “obligations” in your area And we understand players can trigger “actions” on encounter cards in play anywhere. But we don’t know if it being attached makes it more like an obligation or different? And or the fact that this one is not an “action”? Thanks for the help!
