This is an MCH game term that stands for Hero Rarity Cost. The rarity of a team's heroes is quantified as follows, and the total cost of the team is expressed as follows Legendary: 5 Epic: 4 Rare:3 Uncommon:2 Common:1 Novice:1

In duels, this is mainly treated as a restriction regulation. If the rule is HRC12, a team must have a cost of 12 or less to participate.

In quests, it indicates the required cost. If the rule is HRC6 for Lv60, only teams with cost 6 or more can challenge the quest.
