Given that Fortnite Season 3 is nearing to an end, players who have purchased Monarch's Level Up Quest Pack will find it to be the most effective method of earning those final Battle Stars.
This is owing to the fact that its quests require players to locate Level Up Tokens, which allow them to preserve their XP and V Bucks progress while also pushing them up one season level. Aside from that, completing the first week's challenges will provide you access to the Shattered Wings Back Bling. Here's how to finish Monarch's Week 1 challenges and locate every token to ensure that you receive your money's worth out of your purchase.

Token 1 — "Collect Level Up Token northeast of Logjam Lumberyard," As illustrated above, the first Level Up Token may be found on the summit of a snowy mountain, northeast of Logjam Lumberyard. The mountain is just in front of the mansion, which is also home to the grass maze.
Token 2 — "Collect Level Up Token at Sunflower's Saplings": Sunflower's Saplings is a landmark that is surrounded by rows of bushes and is located west of The Daily Bugle, and it is a place where you can collect level up tokens. This token can be found in the center of this bush garden, near the entrance.
Token 3 — 'Collect Level Up Token at Rocky Residence' is the third token, and it can be obtained by visiting Rocky Residence, which is located on the beach side just north of The Daily Bugle. This token can be found in the living room on the second floor.
Token 4 — "Collect Level Up Token at Happy Camper": As the name implies, this site is surrounded by RV campers and is located to the left of Loot Lake, making it a good place to level up. You can find the token in the area between the RVs and the fence.
Token 5 — “Collect Level Up Token at Mighty Monument” You must go to Mighty Monument, which is the island on the right side of the map that has The Foundation's gigantic statue.
