An A-tier clan added in the Huge Update. Every 10th ability/skill used grants a 20% damage boost for 6 seconds. Considered underwhelming by the community compared to S+ clans.
Espada's Edge counts every ability or skill used across all categories. On the 10th ability, you gain +20% damage for 6 seconds. This is a burst window that rewards skill-spamming builds — the goal is to reach the 10th ability count as quickly as possible, then unleash your highest-damage attack during the 6-second window. The community considers Espada underwhelming compared to S+ clans because the 10-ability ramp-up is slow and the +20% burst is shorter-lived than Pride's stacking passive or Monarch's farming efficiency.
Builds that synergize well with clan bonuses:
When starting the game, you receive a random clan. Higher-tier clans are rarer. Use a Clan Reroll item to get a new random clan. S+ tier clans require significant reroll investment.
