Monster Hunter World's first seasonal event is drawing to a close. The ongoing Spring Blossom Fest is set to end on PS4 and Xbox One this Thursday, April 19, giving you only a few more hours to participate in the festivities and earn special rewards.

In addition to a host of new and returning Event Quests, the Spring Blossom Fest introduces a new type of crafting material: Spring Blossom Tickets. These are earned by logging in to the game and completing Limited Bounties, and they can be exchanged to craft new items and gear.
