The plan actually went surprisingly well.
The Orcs had first retreated deeper into the cave to escape from the fire, allowing us to gather outside the cave without getting shot. I then made use of my Aeromancy to blow the smoke deeper into the cave, making sure all the smoke went inside instead of out.
Those Orcs probably thought they could handle the smoke better than the fire and stayed holed up inside the cave despite the smoke filling up its interior.
It took a while but then we heard the sound of coughing coming from inside.
That was followed by a weak squeal before something crashed inside the cave.
The crash seemed to be the cue as the thunderous echoes of multiple Orcs stampeding their way towards the cave entrance could then be heard.
All of us got ready, our vanguards arranging themselves in a semicircle to surround the cave opening.
