  1. Prepare Elusive Clone and Swift Contract while the target is reachable.
  2. Use Shadow Strike for rear access when safe. With the required rank interaction, use Triniel's Dagger after the buffs.
  3. Build Insignias with the normal attack chain, then use Insignia Explosion. Savage Fang is not equipped in this survival preset.
  4. Spend Heartcore opportunities, weave Quick Slice with Savage Roar and use Evasive Stance deliberately for a dangerous attack.

Learn your selected Stigmas at 1, build useful rank-5 foundations, then pursue the later targets. Mastery option slots are at total 8, 12 and 20; total 16 adds an option.
