This goes out to the Judges.
In round 2 and beyond, are we allowed to create and include properly formatted rage powers/domains/hexes/arcana as long as we include the requisite archetype/monster/encounter in our submission and do not exceed our word count?
What if the ninja trick/mystery/eidolon evolution/animal companion etc is archetype specific and fits the theme of the archetype?
The Catfolk Rogue, Grippli Alchemist, and Winter Witch are examples of precedence for inclusion of archetype specific abilities alongside the archetype's entry.
I see the inclusion of Archetype exclusive options as a way to avoid shoe-horning players into giving up choices at certain levels for static, archetype granted pseudo-choice abilities while allowing the archetype to have a unique suite of abilities available to it.
See advice #9 in this thread.
