Mastering Prospector’s Drill: Type, Stats, and Core Mechanics
A Fontaine Forge Crafted for Damage
Type: Polearm
Rarity: 4-Star
Prospector’s Drill belongs to the Fontaine Construction weapon series, known for integrating healing synergies into damage boosts. It functions as an ATK-scaling polearm intended for DPS characters who gain value from elemental damage and offensive buffs triggered through healing interactions.
How to Obtain Prospector’s Drill
This weapon is not available in the standard banner and can only be acquired through limited-time weapon wish banners. As a 4-star weapon, it can be obtained during event banners featuring it in the pool, usually without the option to chart it via Epitomized Path. Players aiming to secure this weapon should monitor event updates or collect it during its featured rotations.
Weapon Stats at Level 90
- Base ATK: 565
- Secondary Stat: ATK% (27.6%)
- Passive Effect – Masons’ Ditty: When the wielder is healed or heals another, they gain 1 Unity Symbol (max 3). These symbols last 30 seconds. Using an Elemental Skill or Burst consumes all symbols and triggers the Struggle effect, granting +7% ATK and +13% Elemental DMG Bonus per symbol for 10 seconds (at Refinement Rank 5). Can be triggered once every 15 seconds.
Unique Mechanics: Unity and Struggle
Prospector’s Drill features a passive that requires interaction with healing to maximize its benefit. Unlike many polearm weapons, the damage buff it provides is conditional. Characters must either receive healing or provide it to gain Unity Symbols. These symbols are then consumed to trigger a powerful timed damage buff.
