Optional Summoner Spells

Exhaust

Exhaust

Defensive option. Exhaust for peeling against enemy divers and assassins and protecting your carries.

Ghost

Ghost

Ghost for extra mobility - great for chasing down fleeing enemies or staying on top of slippery AD carries.

Ignite

Ignite

Offensive option if you are feeling spicy. Grievous Wounds + some damage. Good in early fights and you can score some kills, but reduces your going-in potential. Especially later.

Optional Runes

Grasp of the Undying

Grasp of the Undying

Grasp of the Undying is a solid alternative. You become more tanky over time as your HP grows, you get some sustain and you get some damage as well.

Presence of Mind

Presence of Mind

Triumph is better overall (heal + gold), but if you want to have easier time with your mana, go Presence of Mind.

Demolish

Demolish

If you are into taking objectives, you can consider taking Demolish rune. Usually it is worth it and lets you push turrets quicker. Utility slash team oriented option.

How it works

  1. You rush Thornmail and stack as much Armor as you can.
  2. You become auto-attackers' worst nightmare.
  3. Hit or miss. Works great if the enemy team is full of physical damage and auto-attackers. Less effective against full AP - but still viable since players auto attack anyway.

Playstyle

  1. 🌵

    Rush Thornmail to punish all enemies who auto attack you.

  2. ⚔️

    Stay in fights - the more they hit you, the more they hurt themselves.

  3. 🧰

    Adapt: if they are heavy AP, pivot to regular tank items.

How to play

Thornmail Sejuani

  1. Your Fury of the North (Passive) gives you a massive amount of bonus Armor at the start of combat, allowing Thornmail to deal higher damage to anyone who hits you first.
  2. Engage boldly while your passive is up to maximize reflected damage.

Getting started

  1. Start with Bramble Vest and Ruby Crystal. Rush Thornmail #1, then keep stacking Armor items.
  2. This build is aimed to counter AD comps. Since you don't know the enemy team before loading in, you need to adapt. If they are heavy AP, you can just fall back to a regular tank build.

During fights

  1. Stay in the middle of fights as long as possible. The more enemies hit you, the more damage Thornmail reflects.
  2. If you manage to proc Aftershock during the fight, you are gonna deal tons of damage from Thornmail, try keeping it for it, if you can.
  3. Randuin's Omen is great for engagements - it slows enemies on activation and reduces their crit damage.
  4. Late game, you can consider selling boots for a 6th item - for even more sweet Thornmail damage!
  5. You can use Bandlepipes to give your whole team an attack speed boost whenever you CC enemies. Great synergy with auto attackers.

Runes

  1. Be careful to not waste Aftershock. Try timing it and keeping it for going in. It increases your Armor greatly, which in turn increases Thornmail damage!
  2. You can also take Grasp of the Undying as an alternative rune if you prefer scaling.
  3. Triumph is better overall (heal + gold), but if you want to have easier time with your mana, go Presence of Mind.

Tips and Tricks

Champion

  1. Wait for your Fury of the North (Passive) to be up, before engaging or going in to be more tanky and survive initial burst (or lose less HP).

Riot

  1. Use Arctic Assault to escape bad situations, interupt channeled spells or chase runners.
  2. Melee allies can stack Frost for your Permafrost, keep an eye on who they are attacking.
  3. Save Glacial Prison for encounters where you have teammates present to take advantage of it.
