Kahn didn't waste any more time on planning. He already had a viable and efficient one.
He let the Scarlet Lion guild fight and get exhausted by depleting their strength and their mana so they'll be easy targets to pick off.
Just as the group of hundred adventurers was finally done with the battle and let their guard down, Kahn sprung into action.
[Do it!] commanded Kahn to Ronin & Oliver who were hiding amongst the trees in different directions.
One by one, they both started throwing the fear toxin bombs Kahn had given them and covered all the sides of this battle formation. The outermost layer of their formation was surrounded by the toxin fog in seconds.
"What's this?!" an assassin shouted as soon as he noticed the encircling fog that appeared out of nowhere. Only now did many others also start noticing the fog and put up their guard again.
