"There is nothing more deceptive than an obvious fact." — Arthur Conan Doyle
As the three ultimate abilities landed on Paul, he held block with his sword to reduce incoming damage.
As the three abilities washed over him, his health was reduced drastically, but luckily for him, they were not all direct damaging ultimates, meaning he could cleanse the damage over time of one of them, move out of the AOE of another, and simply heal the damage of the other one.
After healing back to near full health, Paul and the others rushed forward to kill the last three enemy players who had lost any confidence after he had survived.
Despite the original plan being to try to wipe out the healers, it ended up being that the two healers were the last players to die.
