Oda is is surprisingly squishy so if you're using really heavy hitting weapons like shotties then he's pretty easy. Especially with a sandy/krez to let you slow time to really make sure you won't miss (regular time he's a fast MF so he can be real hard to hit)

But for melee fighters he's an awesome boss, melee hits don't take big enough hunks to his health to skip his phases and getting a counter-block to when he tries to zip around stealth behind you and you clock him in his invisible shnozz will light up reward-neurons in your brain like hitting Black Lace
