Last Z Season 2 Frost Core Guide - Frostbanes, Snow Leopards, and Yetis
Quick Answer
Use Frostbane reward attempts as your default Frost Core routine. Join scheduled Hunter Yeti rallies when they occur; use Snow Leopards for first-clear or event rewards within your resistance range.
- Frostbanes · 30 reward attempts per day in week one; 15 with doubled rewards afterward
- Hunter Yeti · 2 rewards daily Monday–Saturday; 5 during Sunday’s event; no Virus Resistance requirement
- Spending · reserve Frost Cores for the Bio Lab checkpoint your Mastery path needs
Frost Core Farming Order
| Target | When to choose it | Limit |
|---|---|---|
| Frostbanes | Default daily Frost Core farming while reward attempts remain | Choose a level your resistance and rally can handle. |
| Snow Leopards | A first-clear reward or seasonal-kill event makes the target useful; otherwise use remaining rewarded Frostbane attempts first. | Stay within your Virus Resistance range; each Snow Leopard costs 8 fuel. |
| Hunter Yeti | Your alliance has a scheduled rally and you have reward attempts left | Rally strength matters; Virus Resistance does not. |
A scheduled Yeti rally can come before finishing Frostbanes. Do not miss the alliance window to follow a fixed target order.
Daily Frostbane Attempts and Fuel Costs
Frostbanes are the Winter counterpart of the Season 1 Boomer-style target.
| Counter / target | Value | What it means |
|---|---|---|
| Week 1 Frostbanes | 30 daily reward attempts | More rewarded rallies to complete. |
| After Week 1 Frostbanes | 15 daily reward attempts with doubled rewards | Fewer attempts do not by themselves mean fewer daily rewards. |
| Frostbane rally | 16–20 fuel | Budget for the rewarded attempts you can complete. |
| Snow Leopard | 8 fuel | Compare the first-clear or event reward before diverting fuel. |
The first week sets your pace for the season. Prioritize your daily Frostbane rewards early: the Frost Cores help you unlock and upgrade seasonal buildings sooner. Completing 30 normal reward attempts and 15 double-reward attempts gives the same daily total at the same target level. Higher-level targets change the payout; the reason to prioritize week one is earlier building progress.
Yetis Need Alliance Coordination
Hunter Yeti gives 2 reward attempts per day Monday–Saturday and 5 during Sunday’s event. Virus Resistance is not required. Join an alliance rally with enough strength for the target while you still have reward attempts.
Rewards can include Ice Blooms, Frost Cores, Snowballs, Modification Blueprints, and resources. Follow the rally leader’s target level and timing rather than trying a stronger Yeti because your Bio Lab level increased.
Where to Spend Frost Cores
Reserve Frost Cores for Bio Lab 26 to unlock level 60 Frostbanes before Combat Mastery. To keep that access when switching, reach Bio Lab 28 first. If Ice Blooms are the missing resource, Smart Greenhouse production addresses that shortage; more Frost Cores alone will not unlock the upgrade.
After reaching your checkpoint, compare Command Post and the cheaper Icy Arsenal or Icy Fort levels. The Bio Lab guide covers that spending decision and the exception for imminent alliance PvP.
Spend seasonal resources before Winter ends: unused Frost Cores and Ice Blooms expire.
