In Arena, an Anvil is a buyable item that gives you a random set of choices instead of a fixed item, letting you spend gold for a semi-random power boost.

What it does

  • Stat Anvil : gives three random permanent stat increases.
  • Legendary Anvil : gives three random Legendary item choices from a specific category, like mage, tank, or support.
  • Prismatic Anvil : gives three random Prismatic item choices.

Why players use it

Anvils are mainly for turning extra gold into power when you already have a build direction, or for gambling on a stronger item spike. In practice, players use them to squeeze value out of gold late in rounds and to fish for high-impact items.

Simple example

If you’re playing a mage and don’t need a normal shop item anymore, a Legendary Anvil can offer three mage-item options so you can pick the best fit.

TL;DR

Anvils in Arena are the mode’s randomized shop upgrade system : one for stats, one for Legendary items, and one for Prismatic items.
