Monster Medals are a unique and powerful mechanic in Dragon Quest Heroes. When you defeat certain monsters, they may drop a Monster Medal. These medals can then be used during battle to summon the corresponding monster to fight alongside you for a limited time, or to unleash a powerful one-time attack or support ability. There are three types of Monster Medals: Savior Medals (blue), which summon a monster to fight for you; Sentry Medals (red), which summon a monster to guard a specific area; and Support Medals (green), which provide a beneficial effect or attack.
You can carry a limited number of Monster Medals, so choose wisely based on the mission and enemy types you expect to encounter. To use a medal, press the R2/RT button (or the assigned button for medals) and then select the desired medal from your inventory. Strategically deploying Monster Medals can turn the tide of battle, especially against large groups of enemies or powerful bosses. For example, a Golem Sentry Medal can hold a chokepoint, while a Healslime Support Medal can restore your party's HP. Experiment with different medals to find the most effective combinations for your playstyle.
