Caster Tamamo part of rate up or no?

All story servants like Sanzang, Waver and Tamamo is on rate up, but if you're aiming for her don't and wait until Halloween when she's on solo.

Any time you have a question similar to this, just click the button that says 'Summon Info', on the bottom left corner of the summon banner. It will tell you exactly which servants are available from that banner, and the chances of getting each servant.
