Diablo Immortal’s Crimson Plane is a limited-time event that enables players to experience the new class, Blood Knight, to complete various objectives.
You can explore the ghastly realm of Sanctuary like never before in this adventurous video game, Diablo Immortal. In addition to a variety of quests and slaying enemies, you can enjoy limited-time in-game events.
One of these events is Crimson Plane, however, it is unlike other in-game events.
Diablo Immortal: Crimson Plane
In order to celebrate the arrival of the new class, Blood Knight, Blizzard is hosting an in-game event called Crimson Plane. This limited-time event gives Diablo Immortal players the opportunity to play the Blood Knight.
A 15-floor gauntlet awaits, and it is occupied by the cruelest minions that the Hells can throw your way.
However, you will not participate in the event with your usual gear, weapons, skills and gems. Instead, players will be provided with a set of pre-selected skills for the Blood Knight.
To progress in the event, you must rely on your vampiric instincts, unstable gear you find and the Chaos Coins that you procure by draining the blood of demonic hordes.
Only unstable gear of Legendary rarity will drop during this event. The items that you receive will complement the skills you begin with, which will enable you to make and tweak your Blood Knight build on the fly.

Floors
Every 5 floors that you complete of the Crimson Plane will reward you with bonus items for your current class. Keep in mind that these rewards resets weekly.
If you complete floors 5 and 10, you will receive a Chaotic Chests. However for completing floor 15, you will receive a Chaotic Chest and a random Legendary Item.
Tasks
In addition to completing floors, you can complete a new task daily for up to 7 days to score progress toward milestone rewards. The following table lists the rewards that you can earn for completing a certain number of tasks:
Number of tasks completed | Rewards |
2 | 10 Aspirant’s Keys |
4 | 1 Telluric Pearl |
6 | 1 Legendary Crest |
7 | Horadric Legacy Sanguine Cosmetic |
When does Crimson Plane conclude?
As previously stated, Crimson Plane is a limited-time event, which means that it is not a permanent feature in Diablo Immortal. Players can participate in the event until Wednesday, 2 August 2023.
It is crucial to note that when your journey in the Crimson Plane is over, all the unstable gear that you collected during the event will vanish.
However, although the items will vanish, you will still be able to experience the Blood Knight, either by creating a new character or by performing a class change with your current character.
