From publisher blurb:
As a champion, you follow a cause. Your cause determines your champion’s reaction, grants you a devotion spell, and defines part of your champion’s code. Causes are split into groups called tenets that share common elements, and in turn the tenets fall into broad types. The champion series of Merlin’s Moments offer a greater selection of tenets and causes.
Oathbound Champion
The Oathbound champion with no cause other than a collection of oaths.
As a variant of the Champion multiclass archetype, the oathbound multiclass archetype greatly improves defences, particularly armor. It’s a great way for a character to gain armor proficiency or a powerful defensive reaction. It differs from the Champion archetype by focusing on oaths rather than a cause.
This variant multiclass champion:
13 multiclass champion feats.
37 Oath feats.
17 Aura feats.
7 devotion focus spells.
