They had five minutes, only five minutes to wound the Warden or face certain death. That sent a wave of urgency through the group, but then they quickly relaxed. Five minutes might seem like a lot, but for them, who would move at a speed above the speed of sound when going all out, it was actually not a short period of time.
In fact, they couldn't last that long when using their marks at all, and since this was not a battle of attrition, they went all out from the start, not holding anything back.
There was no need to think about the five minutes, in fact, that timer was useless to them. Their marks would dissipate long before the five minutes were down, and if they were unable to harm the Warden in that state, then they would never be able to wound him.
"Don't use your transformation, we need it after we wound him." Jin suddenly told Reign who nodded his head.
