Win a battle with just your Leader remaining

Preferably super buff your leader and then just win

Buy 3 Charms from a single shop

Save up your money and buy all 3 charms, you will need around 200 gold to buy all 3.

Deal 50 damage in a single hit

By using the combination of Pimento and spice stones you can stack up a lot of spice in the king moko fight, and of course you could also use the other spice option to get up to 50 spice

Deal 100 damage in a single hit

Using a similar strategy to big hitter

Feed the Muncher a Consume item

Pretty self explanatory, feed the muncher a consumable. Get a consumable that you won't need and feed the big boi

Spare the Naked Gnome

This man will appear in the first fight of the game, you just need to not kill him and win the game, the little man will join your team. This also link to another achievement, so keep him in the team.

Win a run with the Naked Gnome on your team

As per the last section, this achievement just need the Gnome to be in you team at the final boss and winning the run, if you're struggling due to the -1 companion, there is a boss reward that adds one more companion to the run

Stack 20 Shroom on a single target

Easiest way is to use Fungun to get hit and stack up to 20 shroom, there might not be enough time during the fight. Just remember you could hit him with your own cards as well as applying slow to your team.

Stack 15 Snow on a single target

By using the combination of Snowcake and Storm Globe, you'll get 14 stack instantly, all you need to do is just apply 2 or more stack to reach 15 stacks

Survive an attack from King Moko and win the battle

To survive King Moko, you want to try to kill off all of his friends and tank hits with brown hearts.

I,e. using Clunker allies and increasing their health with cards such as gigi's Gizmo

Sacrifice 5 allies in a single battle

Easily doable by Sacrificing Chikichi with other summons.

Stack 5 Block on a single target

Using Blunky and recalling him can stack 5 very easily, you just need to stall the fight to allow you to draw him 5 times

Win a Daily Voyage

Just win the daily Voyage :)

Stack 50 Shell on a single target

Putting an ally behind Kernel is probably the best way to stack this up in combination other shell cards. Putting snow on your allies is also important as your companion might kill the enemies too quickly

Defeat the Frost Guardian with a Scrappy Sword

I did this achievement completely by luck but I believe putting charms on the Scrappy Sword to increase it's attack is the best way to secure the kill such as these charms

Defeat the Heart of the Storm

First of all for this end all achievement, you will need to reach 10 storm strength first.
(you can achieve this by winning with bells active, each win will net you one more storm strength limit)

After this, you will be able to see some glowing shops and treasures. In those glowing nodes, you will need to buy/ take the broken vase component, getting two of them and they will merge into The Lumin Vase.

After all of this, you just need to beat the final boss :)

Note that the secret boss is after defeating the Eye of the Storm battle (so two boss fights in a row), and it's quite tough.

Achieve a 3 Win Streak

This might seem a bit of RNG but to minimise the RNG, obviously play your best but also try to beat the runs without buffing your companions too much. I.e. putting a lot of charms on the companions.
This can help you constantly beating the final boss. Also tailor you next run for the final boss. I.e. if you use smashback, build snow/ ink, etc.

Defeat a Boss without applying Snow to them

Try to use heal more healing or shell in the boss and resist yourself from snowing the boss. I fought using smashback effects is the easiest since the effect requires the enemy to hit you to deal damage.

Win a run with the Snowdweller tribe

Not much to say other than win :)

Win a run with the Shademancer tribe

Again, just win :)

Win a run with the Clunkmaster tribe

Just win:)

Have 12 or more cards in your hand at once

Might seem impossible at first glance, but you could use the combination of trash mechanic whilst fighting Gunkback

Have 30 or more Health on a single unit

Other than just brute forcing it by using health cards, you could use the Jwelberry Charm in combination of Booshu to stack a lot of health

Stack x10 Frenzy on a single target

Using the Clunkmaster tribe, you have access to Junk. Which you can hit Mink Mika with Junk to stack frenzy, also hitting your companion with snow again to slow down your attack with help with the length of the fight

Win a run without any Charms equipped

Self explanatory but one tip is try to pick the path without the charm machines to maximise your power in your deck.

(I might be wrong but I believe applying crowns will also fail the challenge)

Win a run with your pet as your only active Companion

Same as Charmless, try to avoid the paths with companion ice blocks.

Win a battle without any cards left in your deck

To setup, go through as many Muncher as possible, and also when you're buying/ taking cards, take consumable cards. But the final touch for this achievement is it can easily be done whilst fighting Weevil, it can help destroy the final few cards you have left in your deck

Expect for the Sunbringer achievement, I've played around 17 hours from zero knowledge of the game. The achievements aren't too difficult to get but just require a bit of grinding. The bulk of the strategy is hitting your companions with snow to last longer in a lot of the achievements.

The game is very fun and I can't wait for new update.
