Hello Wade,

I went ahead and looked into this for you, and see that Seps has an attack that can cause a sleep status where damage does not wake you up. From your description, this appears to be normal.

I advise checking a community site for more information about Seps and their attacks, which can be found on www.PlayOnline.com under the Community Site tab.

Thank you for your patience and understanding.
