Slyzards are lizard-like Draconids that can fly, and can spit and blow fire at their opponents. They have large claws on their feet and a ferocious kick. They can also emit a sonic blast that will knock Geralt over if he’s caught in it. When on the ground a Slyzard will use its flamethrower-like breath to kill its prey, and while in the air it can spit explosive pellets of fire from its mouth.
