Strategy

 * Tanks benefit most from, particularly when the opposing team has high basic attack damage output. League of Legends calculates Thornmail's reflected damage before armor reduces the damage. This means you can reflect more damage than you ultimately take if you have at least 234 effective armor (i.e. after reductions and penetration).
 * is best used to counter champions that mainly rely on basic attacks such as and.
 * is often overshadowed by the other two high armor items, and, because it benefits only the wearer instead of the entire team and only provides armor.
 * Because of these reasons, it is generally acquired only as a counter against certain champions or against an AD heavy team.
 * Champions such as and  can make great use of the passive effect due to their ability to taunt enemies, forcing enemies to attack them with basic attacks.
