Blasters T
Blasters T (バスターズＴ) is an optional mode introduced in Yo-kai Watch 3 akin to Psychic Blasters. Blasters T can be accessed early on in the story after starting and completing the The Deep Underground Adventure Quest on Nate's side. From then on, Blasters T is accessed via warping to the Cluvian Continent. After the two sides merge, Hailey can also warp to the Cluvian Continent.
Blasters T takes a treasure-hunting approach to the main Blasters formula, with the main Blasters Team assisting out this time as well. Everyone is warped to a new location in the Yo-kai World known as the Cluvian Continent, and the Blasters Camp is set up near an oasis. Talking to Sgt. Burly enables you to go to various Dungeons spread out over the Continent. More Dungeons can be unlocked via either progressing through the main Dungeons or through finding Ruins on the Continent. Boss Signiton can use various Treasures for you, allowing you to increase a Yo-kai's Rank, level them up quickly, or max out their move levels. Whisper can either check records or save your progress. Lil' Yora sells various Auras that can give you different effects for Dungeons.
The main objective of Blasters T is collecting Clu-T-facts from Dungeons, although there is also a small story in it that can be done after completing Yo-kai Watch 3's main story. Clu-T-facts can give different rewards depending on the Dungeon, and each Dungeon has a different rate for getting each of its rewards. The rewards are not predetermined whenever you collect a Clu-T-fact. With Auras, you can either unlock new Dungeons or heavily boost the rate of Clu-T-facts, just to name a few examples.
