Warframe Elite Sanctuary Onslaught Guide

How Does Sanctuary Onslaught Work in Warframe?

Sanctuary Onslaught (SO) and its Elite counterpart (ESO) are challenging Warframe endgame activities. Access them by speaking to Cephalon Simaris, after completing the New Strange quest. Imagine endless hordes of enemies, progressively harder, much like Survival missions. Crucially, SO and ESO lack Life Support modules, relying instead on maintaining a crucial efficiency meter. Killing enemies boosts this meter, and successful completion depends on swift enemy takedowns. Each mission unfolds in distinct “zones,” each lasting 2.5 minutes. Zones conclude with a conduit for progression or a chance to exit the mission prematurely.

Which Warframe should you use in Elite Sanctuary Onslaught?

Elite Sanctuary Onslaught demands careful Warframe selection. While some frames can suffice for standard SO, ESO needs a balanced composition for sustained success. A mix of utility and damage dealers often works best in ESO.

• Utility Warframes:
  • Trinity: Excellent healer, crucial for keeping the team alive. Prioritize a balanced Energy Vampire build for optimal effectiveness.
  • Rhino: Another vital support frame. Maintain Rhino’s Ability Strength buff for improved damage and survivability. Strategic use of Stomp can also help control enemy waves.
• DPS Warframes:
  • Saryn: Effective damage dealer, especially in the enclosed zones of ESO. Maximize spore uptime for continuous damage output. Monitor spore effectiveness as enemies are eliminated.
  • Equinox (Day Form): An alternative DPS option. Equinox’s AoE abilities and team buffs contribute to the squad’s overall effectiveness.
  • Volt: A versatile DPS and utility Warframe, contributing excellent crowd control with his fourth ability. Volt can provide shields to improve team survivability.

Best strategies for Elite Sanctuary Onslaught

Unlike standard Sanctuary Onslaught, ESO requires careful coordination. Solo players find little success.

Have a Premade Squad

Pre-built squads are paramount in ESO. Trinity is crucial for survivability, but one Trinity on a squad wastes potential DPS. Ideally, aim for a mix of DPS frames (Saryn, Equinox, Volt) with a supportive frame (Rhino, Trinity). Find a dedicated group via recruiting chat or forums seeking players with specific Warframes to complement your squad.

Stick Together

Maintain close proximity within your team. This allows for fast revives and synergistic healing/buffing from teammates. Sustained survivability within ESO hinges on close collaboration and shared resources, including revives.

Watch the Efficiency Meter

The efficiency meter is a key metric in ESO. Prioritize consistent enemy takedowns to maximize the meter’s growth. Simultaneously, monitor and utilize each Warframe’s ability cooldowns strategically. Don’t waste efficiency pickups unnecessarily. Effective coordination minimizes wasted resources and enables smooth progression through ESO zones.

Endnote

This guide should equip you with the knowledge to tackle ESO effectively. Clearly define your zone target with your squad, aiming for common targets like eight zones for better loot management. Optimize your builds for optimal performance, and don’t hesitate to adapt strategies based on your team composition. Remember, efficient coordination, proper Warframe selections, and close teamwork are paramount for success in Warframe’s Elite Sanctuary Onslaught.
