Xenoblade Chronicles 2 Torna The Golden Country - Bringer of Chaos Herculean Gibson

This shows a Golden Monster Herculean Gibson fight in Bringer of Chaos difficulty. Hugo typically has the same problem that Morag has with tanking: cannot keep aggro. HOWEVER, Hugo's talent art Imperial Tether will allow him to keep aggro at the expense of health. You can use Hugo's tanking buffs to help survive battles longer while directing traffic. Lora is using Master Scope to break Gibson, who normally has high break resistance. I needed two chain attacks on my first successful attempt. I was on my way to activating a 2nd chain attack when Gibson went down. Used party gauge setup to help build up party gauge faster. Haze is useful in chain attacks to heal the party.

Basic Strategy:
Tank, driver combo, put up orbs, and use Hugo's talent art to keep aggro circle on him. Revive drivers as needed. Do a chain attack. Then try to build up party gauge again for a 2nd chain attack. As shown in this example, Gibson may go down before you get a chance to do a second one.

Haze's Lv3 in a chain attack will heal the party. Use it.
