🧬 Virus Resistance – Season 1 Overview

Virus Resistance is the most important stat in Season 1 of Last War: Survival – The Crimson Plague. It affects nearly every activity in the game, from killing infected to fighting players in PvP.

📌 Virus Resistance is increased by upgrading your Virus Research Institute (VRI) and is capped at 10,000.


💡 Why Virus Resistance Matters

Without enough resistance, your units suffer:

  • ⚠️ Increased damage from infected
  • ⚠️ Combat debuffs in PvP
  • ⚠️ Ineffective city captures and higher troop loss

Virus Resistance is not just a PvE stat. If you ignore it, you’ll lose fights even with strong squads.


🧟 Two Types of Resistance

There are two core areas where Virus Resistance is critical:

👉 PvE Resistance →

  • Infected (mobs & cities)
  • Plague Crisis
  • Campaign missions
  • PvE events

👉 PvP Resistance →

  • City wars
  • Military Base (Outpost) fights
  • Defense against players
  • Troop survivability in war

📈 Resistance Scaling by VRI Level

Virus Resistance increases non-linearly as you level your Virus Research Institute. Below is an approximate curve showing how it scales:

✅ How to Increase Resistance

  • Upgrade the Virus Research Institute (VRI)
    • Lv30 = 10,000 Virus Resistance (cap)
  • Complete events that reward VRI EXP & Immune Protein
  • Focus on VRI first before other seasonal buildings

📉 Power Isn’t Everything

In Season 1, raw power doesn’t win battles — not without Virus Resistance. Players with lower power but full resistance will regularly outperform those with millions more in squad strength.

Here’s a simulated example:

📊 Effective Power vs Virus Resistance

Effective Power Chart

PlayerPower (M)Virus ResistanceEffective Power (%)Notes
Player A1010,000100%Fully effective
Player B204,000~60%Heavily debuffed
Player C302,000~40%Loses to weaker players
Player D1510,000100%Ready for PvP

📌 Takeaway: Even with 30M power, you will lose to 10M players with max resistance if you don’t prioritize the Virus Research Institute.
