How it works

General
  1. You rush Thornmail.
  2. You go full Armor.
  3. Hit or miss. Works only if an enemy team is full of physical damage dealers (preferably auto-attackers).
  4. If an enemy team is full of mages/AP damage, play regular tank build instead.

How to play

General
  1. How is this Thornmail build for Sion different to regular tank builds? Item order, Armor stacking and countering enemy physical damage dealers!
  2. This build is aimed to counter AD comps. Since you don't know the enemy team, you need to adapt in game. It is hit or miss. If they are heavy AP - just play regular tank.
  3. Late game, you can consider selling boots for 6th item - for even more sweet Thornmail damage!
  4. Remember to consume your Grasp of the Undying procs!
Sion Thornmail specific
  1. Shields and HP from Soul Furnace (W) indirectly increases Thornmail's damage as it increases your effective HP and you can take more hits.

Tips and Tricks

General
  1. Remember that your W does % max HP, making it pretty good ability to execute your enemies. Wait few seconds so you can explode, combine that with Flash and you have a nice combo to finish off your enemies.
  2. You can combo Soul Furnace (W) with Unstoppable Onslaught (R). Pop W, wait a second or two, then use your ultimate. Donate W when near your target (you don't even need to hit your R) for maximum damage, or when you land your R.
Riot
  1. You only have very slight turning ability during Unstoppable Onslaught, so make sure to use it in straight paths.
  2. Roar of the Slayer is a great setup ability to land a very powerful Decimating Smash.
  3. The Soul Furnace buff displays how much shield strength is remaining, use this information to time its explosion perfectly.
