This guide is obviously for those lucky enough to get Blitz from ARAM. Also, if you can get some hooks going, this build can get your team snowballing. You may not cs well until you can just r the wave away, but you can keep getting kill gold to fund your build.

I usually take ignite if no one else on my team has it, just incase the other team has a Vlad or Mundo. Either of those two being able to freely heal up isn't good.

So, early game you want to land a hook onto anything. If you have a team with decent cc, it should be somewhat cake to get first blood. Don't spam your q though, because you need mana incase you get cced and need the shield passive. Also, it keeps you from actually watching the enemy. Some people have predictable movements, some just stand there to auto. These are the people you want to hook.

Once you get ROA and some more CDR, you should be able to take over the game a bit. ROA will start stacking and get you to that tanky point. This is also when your hooks need to be more on point. Hooking tanks may not be the best, unless your team has high burst. ARAM is super back and forth, so don't worry if you ace them then get aced, it's the nature of the map.

Alright. If you've hit enough of a late game, you should be surprisingly tanky and bursty all in one. When people see your initial build of ROA, Iceborn, and CDR boots, they may start thinking it's a tank build. In reality, Blitz's r scales decently well with AP and can take nice chunks off squishies. The silence is also good. Keep a good position and if you have flash up, flash and r when you think they may start their spell rotations and win the team fight.
