Winterfest in Hero Wars is underway, but we still have plenty of math to do!
The festive Mysterious Island Map introduces another feature this season — Winter Generators are arriving on the Island! Discover and upgrade these special items on the tiles that produce various rewards over time. Use New Year Candies to start upgrading them, gather more by decorating the Tree, and look for Gingerbread Cookies inside Gifts to push your Generators to their highest tiers.
What are the Winterfest Generators?
These unique Mysterious Island locations are on their own islands to the north of the main body of land. They do not require any Mysterious Island Moves to get to them, but you cannot collect the chests on the island until you unlock them.
What is the Total Amount of Resources That Can be Earned from the Winterfest Generators?
Based on what we know about when each Winterfest Generator will go live, and how long each resource well "refresh," we can do the math on how much total resources can be earned!
We can assume each Winterfest Generator will go live at 2am UTC on the applicable date, and last until the end of Winterfest at 2:00 AM UTC on January 1, 2026.
We will assume they will be full upgraded as soon as they go live:
What Winterfest Generators Should We Level on December 23rd?
Winterfest Baubles
There is no advanced analysis for this option; gold is readily available for most, so you should max this immediately!
Total if upgrading on December 23rd: 108,000
Titan Skin Stones
After the Hero Skin Stone Chests, this is the 2nd most valuable Winterfest Generator when it comes to raw emerald value.
Total if max upgrading on December 23rd: 360,000
Free2Play Total (Tier3) if upgrading on December 23rd: 72,000
Large Skin Stone Chests
This and the Titan Skin Stone Winterfest Generator are the 2 most valuable, when it comes to raw emerald value.
Total if max upgrading on December 23rd: 640
(note: becomes available December 23rd) Free2Play Total (Tier3) if upgrading on December 23rd: 144
Emeralds
2nd WORST Return on Investment; however the most versatile reward
Total if max upgrading on December 23rd: Generator Not Available Until Dec 25th
Absolute Artifact Chests
Pretty good value, and you recoup your investment VERY quickly. Not quite as good as the Titan Skin Stones or Hero Skin Stone Chests, but better than the other.
Total if max upgrading on December 23rd: Generator Not Available Until Dec 27th
Elemental Catalysts
Lowest value of all 5 lanterns. The value is extracted from the other Winterfest spreadsheet assuming that a totem fragment is worth 200k emeralds and can be converted to 350 Elemental Catalysts.
