Grimpus is the new raid boss added to A Universal Time (AUT) Christmas update 4.1 and you need to defeat it to get items needed for Candy Cutlass ability. Not only this, you will also get other exclusive drops and candies that you can exchange for uEvent currency to purchase Holiday Skin Crates.
Grimpus is a "monstrous amalgamation of The Grinch & Krampus" and here is his exact spawn location, duration, and along with the list of drops that you will get by killing him.
AUT: Where To Find Grimpus Location & Drops List
You will find Grimpus in Ice Fortress, the new area added with the A Universal Time Winter update for limited time. In order to go there, you will have to talk to Bawx NPC at the Park in City Center.
Once you are teleported to Ice Fortress, you will have to climb to the top of the mountain in front of you to reach the bridge shown in the image.
Across the bridge, you will find a fortress that you can enter to find Grimpus waiting for you after each hour. However, if he is not there, simply wait or just keep playing the game and wait for "Grimpus Has Spawned," message to appear on top of your screen.
Keep in mind that you will have to deal atleast 10% damage in order to get drops. Here is everything that you can get by defeating Grimpus, along with their probability:
- Candy Cutlass’ Blade — 45%
- Random Event Mount — 7.5%
- Peppermint — 60%
- Candy Cane — 40%
- At least 1 piece of candy is guaranteed to drop
- 1 piece of candy — 20%
- 2 drops of candy — 45%
- 3 drops of candy — 30%
- 4 drops of candy — 5%
Grimpus will leave the game once Christmas event gets over, so make sure to get all the rewards as soon as possible.
