This calculator determines how many kills of the Ultracite Terror you need to reach Level 100 on the SCOREboard, with and without a 50% SCORE boost.
3,000 SCORE per kill
4,500 SCORE per kill
This calculator uses the official Fallout 76 SCORE system formulas. The SCORE requirement increases by 25 with each rank, starting from 1,000 SCORE for Rank 2 up to 3,450 SCORE for Rank 100. The cumulative SCORE needed to reach Rank 100 is 220,275 .
| Factor | Value | Explanation |
|---|---|---|
| Total SCORE for Level 100 | 220,275 | Cumulative SCORE needed from rank 1 to 100 |
| XP per Ultracite Terror Kill | 300,000 | Amount of XP gained from defeating the boss with full XP buffs on |
| Repeatable Challenge | 100 SCORE per 10,000 XP | The "Gain 10,000 XP" challenge reward |
| SCORE Boost | 50% | Bonus SCORE from Fallout 1st or scoreboard rewards |
300,000 XP/kill ÷ 10,000 XP = 30 increments
30 increments × 100 SCORE = 3,000 SCORE per kill
Base SCORE per kill × (1 + Boost Percentage)
3,000 × (1 + 0.50) = 3,000 × 1.50 = 4,500 SCORE per kill
Without Boost: 220,275 total SCORE ÷ 3,000 SCORE/kill = 73.425 kills
→ Rounded up: 74 kills needed
With 50% Boost: 220,275 total SCORE ÷ 4,500 SCORE/kill = 48.95 kills
→ Rounded up: 49 kills needed
Each Ultracite Terror kill requires completing the "Gleaming Depths" raid, which typically takes 20-30 minutes with a competent team. This means:
The boost saves approximately 10.4 hours of gameplay.
You have an alt (a mule account or character) deliberately taken through the raid up to checkpoint 4, the stage just before the snake boss.
This alt then serves as the group leader to enter the raid directly at the snake stage then leave before the encounter start.
TIP: After entering the Raid, kill your character to respawn at the snake checkpoint so you won't have to walk all the way down.
This calculation assumes you're ONLY using the repeatable XP challenge. In practice, you should complete Daily and Weekly challenges :
These challenges also receive the boost percentage, making them even more valuable.
The Ultracite Terror is the final boss of the "Gleaming Depths" expedition, considered one of the most challenging encounters in Fallout 76. Success requires:
