Galio could no longer perform the combo W – Shield of Durand combined with Flash since patch 9.14, as it allows The Colossus able to unexpectedly and effectively start a teamfight.
The LoL community has recently found that this combo would not disappear if you use Hextech Flashtraption from Inspiration branch in patch 11.13. This enables Galio to be able to open a teamfight as before.
To perform this Galio combo, you need to use Hextech Flashtraption
As we all know, Hextech Flashtraption could be used after casting Flash. It is notable that when Flash returns to normal, it is only be locked just for a very brief period of time when Galio uses W. Players can completely cast this skill with Flash to unexpectedly taunt many enemies.
The community eventually found that the reason for this bug is that Hextech Flashtraption is not locked when Galio uses W. This combination will still be performed if you timing it correctly when Flash returns to normal. Since this flash taunt combo was locked about 2 years ago, this is obviously a highly major concern for Galio.
Not only Galio, but Ryze’s ultimate Realm Warp combined with Zhonya’s Hourglass has also returned in patch 11.13. Riot Games promptly fixed this thereafter, and Ryze was no longer able to escape too safely. Presumably, Riot will soon detect the problematic interaction from Hextech Flashtraption to Galio’s Shield of Durand.
