Vergis with 43 Champ
Good for both NM and UNM.
205-210: 4:3 champion
191-194: Counter-attack champion
1-turn delay on 4:3 champion skill. 191-194 champ will be stunned (unless affinity trumps) on first stun attack, so adjust accordingly.
2-turn delay on 4:3 champion skill
1-turn delay on Vergis A2. 191-194 champion will get an extra turn after first stun, then comp will be in sync. Adjust accordingly.
Works especially well with a Sepulcher Sentinel as the 4:3 champion and Skullcrusher as counter-attack champion. As always rotation may vary if true speeds differ.
