The Elub Chieftain Mouse is a breed of mouse found in the Tribal Isles region. They are known to drop Blue Pepper Seeds in Elub Shore. In addition, they also drop an important loot, Ancient Frayed Blueprint. Elub Chieftain mice have been found to be especially attracted to Shell cheese, to the point that any other kind of cheese will simply not suffice.
I have used Ancient Spear Gun Trap with Magma Base and using Shell Cheese as my bait to catch the Elub Chieftain Mouse with Ancient Frayed Blueprint Piece.
