[GAMEPLAY]
I was playing an ARAM as Master Chef Tahm Kench and no matter what I did throughout the game I couldn't "eat" the Rammus on my team.
- Go to the Rammus
- Press the S button (that's the keybinding for Devour - his W)
- Either nothing happened or Tahm would devour whatever was the next closest even if it was farther away.
It happened every time I tried to save him from dying. Teammates thought he was 'too big' but I could devour super minions.
