Horace - Lvl 15 Advancement
General Feat - Terrified Retreat (When you critically succeed at the Demoralize action, if the target's level is lower than yours, the target is fleeing for 1 round.)
Third Implement - Mirror
Greater Weapon Specialization (Your damage from weapon specialization increases to 4 with weapons and unarmed attacks in which you're an expert, 6 if you're a master, and 8 if you're legendary)
Juggernaut (Your body is accustomed to physical hardship and resistant to a wide range of ailments. Your proficiency rank for Fortitude saves increases to master. When you roll a success on a Fortitude save, you get a critical success instead.)
Mirror Initiate Benefit (You learn how to use your mirror to project another version of yourself whose realness is a matter of perspective. You gain the Mirror's Reflection action.)
Mirror Intensify Vulnerability (Reinforcing your mirror lets it play tricks on your enemy's senses as it bends light this way or that. You become concealed to the target of your Exploit Vulnerability as your mirror warps its perceptions. As normal for concealment where your overall location is still obvious, you can't use this concealment to Hide or Sneak.)
Mirror's Reflection (1 Action) Lots of convoluted stuff
