Once the commander finished speaking, Archer spotted the Outrider Captain appearing beside them while panting before helping him onto the beast. The other soldiers charged at the Primordials, who were enjoying killing them with ease.
As that happened, he felt an unknown aura wash over him like it was targeting him and grew confused because he didn't know what it was. After looking around, he couldn't see anything, so he turned his attention to the ongoing battle.
When Archer saw all his soldiers dying to give them a chance to escape, he got angry and tried to rise, but the Dragon's Kiss Poison affected him too much, causing him to collapse back down.
He could only wait and recover as the Anti-Venom was working overtime to heal him. Once he was on the back of the beast, the rider took off as the remaining soldiers rushed forward.
