You will have come to this page because you are creating a character for one of my games. It doesn’t matter whether you are creating a Primary, Secondary or Entourage character, they all need to go through the same basic design phases and conform to the same basic criteria.
You can find the Pathfinder rules here
You must look at the Character Creation Page before you go on to build any character :)
You can find the Pathfinder Mythic rules here
I know this isn't the way it is intended to work but I want a way to mix Mythic and non-Mythic characters together in one game :)
I am really not sure how I am going to do this at the moment - but it might involve the offer of a Mythic Tier INSTEAD of advancing a class level. It might also involve restricting what powers are available at each tier.
A quick analysis made me think that a full Mythic Tier might cost two Class levels. The first level is replaced by the Basic Tier abilities, the second Class level is replaced by the Mythic Path abilities. Really not sure about this though - as Paizo think that two Mythic Tiers is about equivalent to +1ECL..
