its possible at gamma lvs 4-8 

@Night-6315 i used to think any combo using both gammas was bad. But tbh gamma combos are really good. The recharge isn't that long and and dmg output of gamma gamma combos is insane this making it worth it however i wouldn't go for it every time. Assess the situation and determine if you think its worth it

@no_life45678 in 1v1s it's viable, but in team fights your gonna get murdered trying to do that combo

@Night-6315 once again. Even in team fights it depends on situation. Being able to take one person out of the fight entirely is incredibly valuable and a great way to turn a losing 3v3 into a winning 3v2

@@JinYinZ im guessing you mean you get stuck in animation. Use a 2nd beta to cancel the end lag of beta 1 and then cancel the 2nd beta into gamma
