How do I use Contagion?

Are you absolutely sure your pet's on Obey? When your pet's on Sic the options will be grayed out. I don't recall if it's the same story with Steady. Another thing I can think of, which may seem like a dumb second question but, you ARE using Garuda-Egi right? Skills will also be grayed out if you have Ifrit or Titan out and have Garuda skills on your hotbar

Double check and make sure you're setting your pet to Obey.

It's not a dumb question but my answer is dumb! I was using Titan. Thanks
