"Wait, what sort of plan do you have for such a desperate situation?"
They saw very clearly in their ghost form that Li Yao was having a hard time even defending himself, he could barely attack at all.
He could only roll and leap backward to loose an arrow. With the boss's healing ability, he could only stay on par with it.
Under these circumstances, it seemed nearly impossible to defeat this creature.
Of course they knew that Li Yao still had a summoning scroll from a familiar, but under these circumstances, summoning a Treant would be of no use.
The Treant would basically be one-hit kills, not to mention the healing Treant. With the boss's frenzied state, it could kill in one hit, there was basically no use for it.
Li Yao again narrowly dodged the boss's charge, he had even reached the edge of the spiral corridor.
