Mercury's Treads is an advanced item available in Classic and Dominion mode.


  • Good boots to build when the enemy team has decent AP damage and a lot of CC.
  • Seen very often on tanks because of the efficient Magic Resist and Tenacity allows them to get into the battle without worrying too much about being CCed to death.
