How to defeat Chameleos in MHF2 or in MHF Unite

Here's a very neat tactic to fight him with a LS. Don't attack him straight on face to face. Instead come from the side of this face at a 90 degree angle and do a downward slash two times to reach his head and if he doesn't flinch, roll quickly away and repeat this.

If he does flinch, return back and finish him off with some combos in the head then repeat.

You can almost become invisible from all of his hits if you master this tactic.
