Seasonal Enemies
Learn how to fight Frostbanes, Snow Leopards, and Wandering Yetis efficiently during Season 2: Everfrost.
Learning Objective
Understand what each Everfrost enemy is, which rewards it provides, how Virus Resistance affects progression, and how to spend Gas efficiently throughout Season 2.
Introduction
Everfrost replaces several familiar world-map enemies with frozen seasonal versions.
You will encounter three major enemy types:
- Frostbanes — your primary daily farming target
- Snow Leopards — valuable for first-clear rewards and seasonal objectives
- Wandering Yetis — powerful alliance rally bosses with limited reward-earning attacks
These enemies are directly tied to Frost Cores, Mastery EXP, Virus Resistance, seasonal progression, and alliance activity.
The most important rule is simple:
Complete your Frostbane farming before spending large amounts of Gas elsewhere.
Quick Priority Guide
| Priority | Enemy | Best Reason to Attack |
|---|---|---|
| 1 — Essential | Frostbanes | Best routine source of Frost Cores |
| 2 — Situational | Snow Leopards | First-clear rewards, objectives, and additional seasonal resources |
| 3 — Alliance Priority | Wandering Yeti | Large rally rewards, Personal Glory, and alliance/state rewards |
Recommended Daily Order
- Complete your available Frostbane reward kills.
- Clear any newly unlocked Snow Leopard levels.
- Join successful Wandering Yeti rallies whenever your alliance organizes them.
- Spend remaining Gas on seasonal objectives or other account priorities.
Frostbanes
What Are Frostbanes?
Frostbanes are the Everfrost replacement for Boomers.
They are the single most important seasonal enemy because they provide the largest dependable supply of Frost Cores. Frost Cores are required for seasonal building progression, including upgrades that increase your Virus Resistance.
As your Virus Resistance rises, you can attack higher-level Frostbanes. Higher levels generally provide better rewards, creating a progression loop:
Farm Frostbanes → earn Frost Cores → upgrade seasonal buildings → increase Virus Resistance → unlock stronger Frostbanes
Frostbane Rewards
Frostbanes may provide:
- Mastery EXP
- Snowflakes
- Frost Cores
- Blueprints
- Resources
Reward amounts increase with enemy level.
Why Frostbanes Are the Top Priority
Frostbanes should normally receive your first seasonal Gas each day.
Their Frost Core rewards support nearly every other part of Everfrost progression. Falling behind on Frostbane farming can slow your seasonal buildings, Virus Resistance, and access to higher-level enemies.
SIN’s Priority Call
When Gas is limited, attack Frostbanes before Snow Leopards or ordinary map enemies.
How to Farm Frostbanes Efficiently
- Complete your Frostbane kills soon after daily reset.
- Attack the highest level your Virus Resistance allows you to defeat efficiently.
- Keep your seasonal resistance buildings upgrading whenever possible.
- Avoid wasting marches on levels that cause excessive troop losses.
- Use alliance coordination when stronger targets are difficult to defeat alone.
- Check whether an event or seasonal objective is awarding extra points before spending additional Gas.
Daily Reward Limits
During the opening week of Everfrost, the seasonal reward structure may require 30 Frostbane kills per day.
After the opening week, the same daily reward track may require only 15 kills per day.
Because seasonal mechanics can vary by rollout or state, confirm the active daily counter shown in your game before spending additional Gas.
Frostbane Mistakes to Avoid
- Spending most of your Gas before completing Frostbane rewards
- Ignoring Virus Resistance upgrades
- Farming lower levels after stronger efficient levels are available
- Continuing beyond the reward limit without an event or specific objective
- Taking unnecessary troop losses for a small increase in rewards
Snow Leopards
What Are Snow Leopards?
Snow Leopards replace the normal Zombies encountered during earlier stages of the game.
They also provide seasonal rewards, including Frost Cores, but usually offer fewer Frost Cores than Frostbanes. Their greatest value often comes from first-clear rewards when you defeat a new level for the first time.
Snow Leopards are therefore a secondary farming target rather than your first daily priority.
Snow Leopard Rewards
Snow Leopards may provide:
- Mastery EXP
- Snowflakes
- Frost Cores
- Hero EXP
- Resources
- First-clear rewards
- Personal Glory or seasonal objective progress, when applicable
First-Clear Strategy
As your Virus Resistance increases, return to the map and look for newly available Snow Leopard levels.
The first defeat of each level may provide substantially better value than repeating a level you have already cleared.
This is especially important for free-to-play players because first-clear rewards can provide additional progression without requiring repeated farming.
How to Farm Snow Leopards Efficiently
- Complete Frostbane rewards first.
- Clear each newly unlocked level at least once.
- Check the first-clear reward before attacking.
- Use alliance assistance when a newly unlocked level is difficult.
- Farm additional Snow Leopards only when required for an event, objective, or reward track.
- Do not repeatedly spend Gas on low-value levels when no first-clear or event reward remains.
Snow Leopard Priority
Snow Leopards are a moderate priority.
They become valuable when:
- You have finished your Frostbane farming
- Your Virus Resistance unlocks a new level
- A seasonal event requires Snow Leopard attacks
- You need first-clear rewards
- You need additional Mastery EXP, Hero EXP, or seasonal resources
Snow Leopard Mistakes to Avoid
- Farming them before completing Frostbane rewards
- Forgetting to claim newly available first-clear rewards
- Repeating old levels without checking the value
- Assuming they are always a better Frost Core source than Frostbanes
- Ignoring alliance help on difficult first clears
Wandering Yeti
What Is the Wandering Yeti?
The Wandering Yeti is a powerful mobile world boss that appears throughout Everfrost.
Unlike Frostbanes and Snow Leopards, Yetis are designed for alliance rallies rather than routine solo attacks. Success depends on rally strength, troop coordination, participation, and selecting an appropriate Yeti level.
Higher-level Yetis can provide significantly better rewards, but they can also send large numbers of troops to the hospital.
Wandering Yeti Rewards
Successful Yeti attacks may provide:
- Large amounts of Frost Cores
- Icebloom
- State rewards
- Discovery rewards
- Personal Glory
- Additional seasonal or event rewards when active
Reward-Earning Attack Limits
Under normal conditions, players may receive rewards from:
- 2 successful Yeti attacks per day
During the Sunday Endless Night event, this may increase to:
- 5 reward-earning attacks
Always check the active counter in the game, since event rules and rollout details can change.
How to Fight Yetis Efficiently
- Join alliance rallies whenever possible.
- Let one of your strongest rally leaders start the attack.
- Choose a Yeti level the rally can defeat reliably.
- Fill rallies quickly so the alliance does not lose opportunities.
- Use your strongest appropriate march unless leadership gives different instructions.
- Watch hospital capacity before repeated attacks.
- Prioritize successful rallies over attempting levels that are too strong.
- Save reward-earning attacks for organized rallies with a realistic chance of victory.
Alliance Coordination
A strong Yeti routine should include:
- Designated rally leaders
- Recommended Yeti levels
- Clear rally times
- Fast participation
- Hospital-capacity reminders
- Location sharing in alliance chat
- A plan for the additional Sunday reward attacks
Leadership Note
Never ignore an organized Yeti rally simply because the target looks difficult. Check who is leading, what level is being attacked, and whether the alliance has enough strength. Missing a successful rally can mean losing some of the season’s best limited rewards.
Community-Reported Mechanics to Verify
Unofficial community guides report two additional mechanics:
- Rewards may require participation in the rally that delivers the final successful defeat.
- Starting and immediately cancelling a rally may redirect a Yeti that is moving toward your base.
These behaviors should be treated as community tips until confirmed in State 683. Do not rely on them when valuable troops or rewards are at risk.
Yeti Mistakes to Avoid
- Starting a rally that the alliance cannot realistically win
- Joining weak rallies after using all reward-earning attacks
- Ignoring hospital capacity
- Using poor troop formations when stronger options are available
- Missing Sunday’s expanded Endless Night reward limit
- Assuming damage alone guarantees rewards without checking the active rules
Virus Resistance and Enemy Levels
Virus Resistance determines which levels of seasonal enemies you can challenge effectively.
Increasing resistance allows you to:
- Attack stronger Frostbanes
- Unlock additional Snow Leopard first clears
- Participate in more difficult Yeti rallies
- Earn stronger seasonal rewards
- Progress more quickly through Everfrost objectives
Your enemy-farming plan and seasonal-building plan should support one another.
Do not treat them as separate systems.
Best Use of Gas
Gas is one of your most limited daily resources, so every attack should have a purpose.
Strong Uses of Gas
- Completing Frostbane reward kills
- Earning a new Snow Leopard first-clear reward
- Participating in a successful Yeti rally
- Completing a high-value seasonal event objective
- Attacking a stronger enemy level that provides meaningfully better rewards
Weak Uses of Gas
- Repeating Snow Leopard levels with no first-clear or event value
- Continuing Frostbane attacks after the reward limit without a reason
- Joining Yeti rallies that are unlikely to succeed
- Attacking levels that cause excessive hospital losses
- Spending Gas before checking active seasonal objectives
Final Recommendation
Everfrost enemy farming is not about attacking everything on the map.
It is about using Gas in the correct order.
Frostbanes build your seasonal foundation. Snow Leopards provide progression milestones. Wandering Yetis reward alliance coordination.
Complete the highest-value attacks first, keep Virus Resistance moving, and avoid spending limited attacks or Gas without a clear reward.
Farm with purpose.
Coordinate with your alliance.
Keep the season snowballing.
