I'm sure this has been asked before, but searching for a thread on this site is laughable; so I'll just ask my question and be on my way.
Can I use Zi Mei's E: to give Multiple: 2 to an attack that already has multiple? does one supersede the other or are they both considered to be on there and can both be played. I remember this issue being brought up with Paul's Gi giving Stun to an attack with stun, allowing the one attack to effectively stun twice. I don't know however if it would still apply to this situation or if the wording of stun allows for an exception.
