Mkulme didn't chase after Kilio after he ran off to face Tumwa. Instead, he came to Roho who had just been freed by the Disorient status. Without pause, his fists that held the karambits struck Roho repeatedly.
His repeating punches were very fast and were executed as if they were one rapid movement. Peniel informed Jack that those punches were Battle Monk's non-standard skill, Chained Strikes. This skill's damage increased with each connected strike. Jack counted Mkulme delivering twenty consecutive punches, which Peniel said was the number of strikes delivered by a Max-level Chained Strikes.
With Mkulme harassing Roho at melee range, Roho was denied the chance for casting a spell.
Kilio who had been knocked away by Tumwa was immobilized when Tumwa cast Hell Whip, a Warlock's spell. The fiery whip locked him in place, preventing him from assisting Roho.
