TL;DR
- Rubies upgrade weapons to tiers 2-3 but cannot reach maximum level
- Sentinel Barracks contains two rubies – one on main path, one in secret area
- Holy City of Aratum requires shield mechanics and underwater exploration
- Siege – Part 1 features four rubies with complex environmental puzzles
- Strategic collection prevents weapon progression bottlenecks
Rubies represent one of the most critical progression resources in Doom The Dark Ages, serving as the primary currency for weapon enhancement. While these crimson gems cannot elevate your arsenal to maximum power levels, they enable significant upgrades to secondary and tertiary weapon tiers that often provide more practical combat advantages than final-tier improvements. Many mid-game weapons actually perform better at Ruby-upgraded levels than their fully-maxed counterparts due to superior ammo efficiency and handling characteristics.
Strategic resource allocation becomes essential since Rubies remain finite throughout your campaign. These valuable items remain deliberately concealed across various chapters, requiring thorough exploration and puzzle-solving acumen. Understanding their strategic distribution patterns helps optimize your collection efficiency and weapon upgrade sequencing.
The initial Ruby acquisition opportunity emerges during the Sentinel Barracks segment, designated as Chapter 4 in your mission progression. This area contains precisely two rubies, each requiring different approaches for successful retrieval.
Aratum’s sacred urban landscape harbors two additional rubies, each positioned within distinct environmental contexts requiring specialized acquisition methods.
The Siege – Part 1 chapter presents the most substantial Ruby harvesting opportunity with four total gems available, though their retrieval proves considerably more complex than previous locations. Consult our comprehensive Weapons Unlock Guide for complementary equipment strategies that enhance your collection efficiency.
Mastering Ruby collection requires understanding nuanced game mechanics and developing systematic exploration habits. For broader strategic context, our Complete Guide offers complementary progression insights.
Efficiency Optimization Techniques: Always complete area clearance before Ruby retrieval to avoid combat interruptions. Utilize the Class Guide recommendations for optimal mobility and exploration capabilities. Methodically scan environments for atypical geometry or coloration that often indicates hidden passages.
Common Collection Pitfalls: Many players prematurely abandon underwater sections without thorough perimeter examination. Others overlook vertical space assessment, missing overhead interactive elements. Always allocate 15-20 minutes per major area for comprehensive exploration to ensure no Ruby locations remain undiscovered.
The solitary Kar’Thul Marshes ruby presents a complex dimensional puzzle requiring precise execution. Journey to the marked location and enter the mysterious chamber, which transports you to an alternate reality housing the actual challenge. Begin by plunging into the water to reach the elevated platform. From this vantage point, accurately launch your shield toward the distant crimson lock mechanism.
Descend to the lower level and carefully align the dual Cosmic Eye frames, ensuring perfect synchronization before deploying the Shield Saw to fracture the framework. Re-enter the water to return to the platform summit, then make your final leap to claim the ruby. Common mistake: Failing to maintain shield deployment during the alignment process.
Harbor of Souls features a single ruby secured behind a rapid-response puzzle mechanism. Follow primary objectives to the designated zone, then utilize the central elevator for vertical access. Proceed to the platform featuring the oversized crimson activation button.
Position yourself on the button and precisely target the opposing energy modules with your Shield Saw. Upon successful impact, the ruby-containing chamber will unlock. Critical strategy: Maintain shield deployment until securing the ruby to prevent door resealing. Estimated completion time: 2-3 minutes with proper execution.
Chapter 20, Resurrection, contains three rubies distributed across the environment. Here’s your comprehensive acquisition strategy for Doom The Dark Ages.
