Hero Medals

Hero Medals in CoD function largely like the CC Soulstones.
 * Collect Hero Medals for the different non-shardable heroes from special events.
 * Hero Medals are listed under the Warehouse Hero Tab, and each type takes one Warehouse slot to store.
 * Collect 100 Hero Medals of a specific type to trade for one hero of that type in that hero types' Compendium Biography page.
 * Sell unwanted Hero Medals for 300 Honor each.
