Understanding Saros Permanent Upgrades and Progression
Saros permanent upgrades are core abilities that persist between cycles, fundamentally shaping how you fight and explore. While you cannot miss them—each sits on the critical story path—it pays to know when they appear so you can plan efficient routes and remember blocked areas worth revisiting. This Saros upgrades guide focuses on six key abilities: Jump Network, Grapple, Overdrive, Parry, Eclipse Thread, and Blazing Strike. Because they are tied to specific biomes, bosses, and NPC interactions, you can treat them as milestones for your overall progression. As you learn how to unlock Saros abilities in order, you will steadily gain tools for mobility, survivability, and damage spikes. For faster advancement, focus on reaching each biome’s critical objective instead of full clears, using your growing kit to bypass enemies when possible and conserve resources for boss encounters.
Jump Network and Grapple: Movement and Fast Travel Foundations
Your first major Saros permanent upgrade is the Jump Network, unlocked after defeating the Prophet at the end of the Shattered Rise biome. Once the boss falls, you will be directed back to the Passage; from there, the Jump Network activates, enabling fast travel between discovered Jump points via the World Dial. For efficient progression, prioritize activating every Jump point you pass so backtracking to earlier biomes or objectives becomes painless. The Grapple comes later, after you complete the Ancient Depths and reach the Colony ruins. Follow the story prompts and interact with the indicated terminal to unlock this traversal power. Grapple points are marked with distinctive purple or blue lights. While Grapple has no direct combat function, it significantly speeds up traversal and grants access to side paths and shortcuts. When planning routes, mentally note every unreachable grapple anchor so you can return once this upgrade is unlocked.
Overdrive and Parry: Combat Powerhouses You Should Prioritize
Overdrive is a powerful offensive ability gained after speaking to Eli in the Shattered Descent biome. Once unlocked, it charges over time and lets you unleash devastating bursts of damage. For effective use, save Overdrive for elite foes, Overlords, or dense enemy packs, aiming to synchronize it with weapon synergies and damage windows. Because this ability can be enhanced via armor upgrades and the skill tree, investing in Overdrive-related perks is a strong strategy for consistent high DPS runs. Parry unlocks when you power up the Carcosan device for Alab in the Blighted Marsh biome. It lets you melee Nova projectiles back at enemies, turning incoming fire into an offensive tool. Timing is crucial: practice parrying basic projectiles before relying on it against bosses. Like Overdrive, Parry can be upgraded, so if you prefer a reactive, skill-based playstyle, lean into Parry-enhancing nodes to increase safety and counterattack potential in tougher biomes.
Eclipse Thread and Blazing Strike: Late-Game Mobility and Destruction
The Eclipse Thread is acquired in the Desecrated Fortress biome by triggering the Eclipse at an otherwise uncrossable gap. This upgrade allows you to ride Threads during Eclipses, crossing vast spaces that previously walled off routes, secrets, or shortcuts. As soon as you unlock it, mentally revisit earlier areas where large chasms blocked progress. Efficient players weave Eclipse routes into their runs to reach high-value encounters or bypass dangerous zones. Blazing Strike is your final major upgrade, obtained after completing Act 2 and entering the Yellow Shore biome. This enhanced melee lets you break yellow barriers, smash locked containers, and teleport to staggered enemies, while also increasing melee damage overall. Its utility is twofold: opening new environmental paths and enabling aggressive close-quarters play. To make the most of Blazing Strike, scan each biome for yellow obstructions you skipped earlier and consider hybrid builds that leverage both ranged damage and empowered melee finishers.
Maximizing the Impact of Saros Permanent Upgrades
Once you know how to unlock Saros abilities in sequence, the next step is optimizing how they interact. Use the Jump Network to create efficient loops through biomes as new upgrades come online, revisiting earlier obstacles with Grapple, Eclipse Thread, and Blazing Strike. In combat, treat Overdrive as your spike tool for bosses or swarms, while Parry rewards precise timing and reduces chip damage during longer fights. Because Saros permanent upgrades are complemented by armor and skill tree enhancements, tailor your build around the abilities you lean on most. Overdrive and Parry both benefit from targeted investment, turning already-strong tools into run-defining strengths. By planning your path around these milestones and revisiting gated areas once each upgrade is unlocked, you streamline progression, increase your odds against Overlords, and move steadily toward late-game challenges and their associated trophies.
