Mercenary and Reinforcement Selection Guide

Separate the hired Mercenary who joins solo play from the Reinforcement tied to a skill trigger. Choose both by missing role and activation, not raw damage, in an expansion-first audit.

Verified patch: 3.1.15 decision checksExpansion-first
QUICK ANSWER

Match the hired slot to missing mitigation, control, support, or damage, and bind Reinforcement to a skill you reliably cast. Change one Mercenary node at a time, comparing survival, core uptime, and solo clear time.
