Decaying Winter ERU Boss Wave Overview
The Decaying Winter ERU event, also known as the Civil War or Freedom Fighters Boss Wave, is one of the seven major boss wave events in Last Strandeds. This event is exclusive to Holdout Mode and triggers randomly through the game's RNG system, appearing in approximately 14.7% of runs. When this event begins, players face a combined assault of Freedom Fighters and ERU tactical units.
The event consists of roughly five waves of escalating difficulty, culminating in a final boss fight against Rhyer. Unlike standard Scavenger waves, ERU enemies possess advanced close-quarters combat (CQC) training, making them significantly more dangerous than standard foes.
This boss wave only occurs in Holdout Mode. If you are playing standard Normal Mode events like Scavenger's Raid or Scav Warfare, you will not encounter the ERU Civil War event.

Detailed Enemy Statistics
| Enemy Type | Health | Light Dmg | Heavy Dmg | Special Ability |
|---|---|---|---|---|
| Mil-axe Fighter | 175 | 8 | 25 | CQC Grapple/Parry, Stim Heal |
| Akimbo Glock Fighter | ~150 | 6/shot | N/A | Rapid Fire, Stim Heal |
| ERU Scout | 150-200 | 11 | 44 | Absolver (33 Dmg), Feint Attack |
| Rhyer (Boss) | 699 | 10 | 40 | Infinite Dropslide, Sprint Speed |
Status Effects Applied on Hit
All enemies in the ERU wave have a 10% chance to apply debilitating status effects on hit. The specific effects vary by enemy type:
| Enemy | Possible Status Effects |
|---|---|
| Mil-axe Fighter | Bleed, Cripple, Artery Bleeding, Fracture |
| Akimbo Glock Fighter | Bleed, Cripple, Artery Bleeding, Fracture |
| ERU Scout | Bleed, Artery Bleeding |
| Rhyer | Bleed, Cripple, Artery Bleeding, Fracture |
ERU Scouts are the most dangerous standard enemies due to their unique Feint Attack. They can fake out an attack and backpedal to retaliate, punishing players who parry too early. Watch their movement patterns carefully before committing to a counter-attack.
Rhyer Boss Fight Strategy
Rhyer is the final boss of the Decaying Winter ERU event and represents a classic "Fragile Speedster" archetype. While he has the lowest HP pool of any boss in the game at only 699 Health Points, his extreme mobility and damage output make him a lethal threat.
Rhyer's Key Characteristics
Rhyer rushes in at the end of the Freedom Fighter's wave alongside a battalion of six ERU Scouts. His movement speed is exceptionally fast, and he can dropslide infinitely, making him difficult to track and hit consistently. His mask displays the Japanese characters "熱意" (netsui), which translates to "enthusiasm" or "zeal."
Despite having 25% firearms resistance, Rhyer can still be effectively countered with the right approach. His attacks can be parried, but he recovers almost instantly, similar to the "bucketman" enemy type.
Rhyer deals 3x more damage to allies compared to standard enemies. He acts as a massive distraction during the final wave. Prioritize eliminating him immediately before clearing out the remaining ERU Scouts to prevent devastating team wipes.
Recommended Counter-Loadout
| Weapon Category | Recommendation | Reason |
|---|---|---|
| Primary | High RPM Rifle/SMG | Large enemy counts require sustained fire |
| Secondary | Heavy Melee (Parry) | Punish Rhyer's dropslides and Scout feints |
| Utility | Medkits & Bandages | Counter Bleed/Artery Bleeding effects |
| Stim | Damage Boosters | Burst down healing enemies quickly |
Step-by-Step Survival Guide
Wave Preparation
Stock up on high RPM weapons and medical supplies before the event triggers. Ensure your team has a mix of ranged and melee capabilities. The ERU event cannot be predicted, so maintaining readiness throughout Holdout Mode is essential.
Early Waves (Fighters)
Focus on eliminating Mil-axe Fighters first while maintaining distance from Akimbo Glock Fighters. Use cover to avoid the Glock's 34-bullet spray. Apply consistent damage to prevent enemies from using their Cocktail Perithesense stims.
Mid Waves (ERU Scouts)
When ERU Scouts spawn, switch to a more defensive playstyle. Do not rush their attacks, as their Feint mechanic will punish aggressive parrying. Space out enemies and pick them off one by one using ranged weapons.
Final Boss (Rhyer)
When Rhyer spawns with six ERU Scouts, immediately focus all firepower on Rhyer. His low HP pool of 699 means a coordinated team can burst him down quickly. Clear the remaining Scouts afterward.
The key to surviving the ERU Civil War is target prioritization. Never let Rhyer roam freely, as his speed and 3x ally damage modifier will quickly dismantle an uncoordinated team. Call out his position and focus fire immediately.
Pre-Raid Checklist
ERU Boss Wave Preparation:
- Carry a high RPM weapon with ample ammunition
- Stock medical supplies for Bleed and Fracture
- Equip a reliable melee weapon for CQC parrying
- Coordinate target prioritization with your team
- Identify cover positions for Glock Fighter waves
Frequently Asked Questions
Q: What is the Decaying Winter ERU Boss Wave?
The ERU Boss Wave, also called the Civil War, is a Holdout Mode exclusive event in Last Strandeds. It features Freedom Fighters and ERU tactical units attacking in waves, culminating in a fight against the boss Rhyer. It has approximately a 14.7% chance to spawn.
Q: How much health does Rhyer have in the ERU event?
Rhyer has 699 Health Points, making him the squishiest boss in Decaying Winter. However, his extreme speed, infinite dropslide ability, and 25% firearms resistance make him difficult to hit and take down without coordination.
Q: Can ERU enemies heal themselves during the fight?
Yes, most enemies in the ERU wave use Perithesene stims. Mil-axe Fighters and Akimbo Glock Fighters use the Cocktail variant to restore full health when low. ERU Scouts use an ERU Perithesene Stim that heals them to maximum within seconds when they reach half health.
Q: What is the best weapon type for the ERU Boss Wave?
High RPM (rounds per minute) guns are strongly recommended. The waves spawn large numbers of enemies that require sustained fire to break through their healing stims. Additionally, a strong melee weapon for parrying ERU Scouts and Rhyer is essential for close-quarters survival.
