Events

From time to time, special event quests will appear under the Special Quest tab in Quests as limited time period campaigns in Bloody Blades. These provide players access to event-exclusive quest maps and the opportunity to gather character cards which do not appear outside of these event maps.

Item Collection Event
By completing the event quest maps, players will be able to obtain two kinds of tokens; the Event Gacha token and the Event Milestone tokens.

In most events, the performance of players will be determined by the total number of Event Milestone tokens they have collected as the event campaign progresses, which will decide what kind of rewards players will gain when they have collected a specific number of Event Milestone tokens. Rewards for higher tiers of Event Milestone tokens collected tend to include a SSR Asuramaru, which can be used to increase the skill level of existing cards.

Event Gacha tokens can be used to complete the special 22-draw  Event Gacha (イベント), where players will be able to obtain a copy of a SSR event-exclusive card out of the 22 draws.

In some events, players may improve their performance at these events by successfully summoning specific characters that are specially pre-released for the event, where having either one or both characters released will provide additional event items collected for every wave cleared in a successful quest run. If players possess both cards, they will be able to get a greater amount of bonus event items as well. This special effect remains active for the rest of the duration of the event campaign as long as the player has the card(s) in their deck while playing the event quest.

Possessing multiple copies of the same helper card does not hold any advantage, but having both cards will yield a greater percentage of additional Event Gacha tokens obtained.

Battle Event
Battle events require the player to clear the final quest of the event map under Demon difficulty (the hardest quest) to secure the featured card of the event through a drop.

In the The Queen's Advent and Supreme Ruler of the Abyss events, drops were not guaranteed, and the only sure way to obtain the featured card was through getting a 3-star ranking for the last quest. From the 面妖なる血の美食家 onward, players were then guaranteed a 100% drop should they clear the final quest, regardless of whether they have used demon stones to revive or not.
