Here you need to complete room 20 for each character and defeat the final boss.





Sir bunalot— the first character, perfect for getting to know the game.
Abilities: health increases by 10, and at the start of the battle, five shields are provided.





Scrappy— the second claw is a magnet. One of the most powerful characters.





Felina — starts the battle with 1 strength and a cat that attacks enemies when she takes damage.





Count Clawcula — cannot use shields, but heals for 10% of the damage he deals.





Dolly— to unlock, you need to deal 20 damage to yourself. Deals damage to self and the same to the enemy, health increases by 50%, but block is reduced by 50%





Benny Beaver — to unlock, you need to gain 40+ shields in one go. Starts the battle with Beaver Dam, 4 strength, but health is reduced by 30%.





Bernie — to unlock, you need to accumulate 500 coins. The easiest way to accumulate 500 coins is after room 20, using the coin token and subsequently perks for coins. Uses the claw based on time but gets 100% more coins.





Squiddy— to unlock him, you need to fill the machine with liquid 5 times in one battle. You need to use the water token, and later in the battle, use the water bottle several times.
Abilities: the second claw — tentacles; when the machine is filled with water, gains 1 strength.





Garbage Greg— you need to collect 30+ items, also easiest after room 20. After the turn, removes 50% of items from the machine (items are saved after the battle), increases damage by 2% for each item in the deck.





Anne Bunny — to unlock, you need to use one item three times in a row.
Second claw — harpoon; uses the harpoon twice; if the harpoon takes 1 item, gives 5 shields.





Chief Bunner — to unlock him, you need to save 50% block between turns. You need to find the «Block Master» perk twice, which saves 25% of the block; after that, the Commander will be unlocked immediately.
Saves 50% shields in the round, gives a charge for every 3 shields.





Cuddline Floofington — +15 fluff in the machine; when collecting more than 7 fluffs, gets hysterical.





ToxicCarl — enhances the flask for each kill with poison; for applying poison, you get +1 poison.





Mr. Boney - does not increase strength, but critical damage is 100% higher; gives bonuses in slot machines.





Astrobun — second claw — antigravity cannon.





Baroness von Frost - deals 2% more damage from frost; when dying from frost damage, the effect is transferred to another enemy.





Nanny Fran— has only 50 health, starts the battle with a pet.





Hare L. Quinn - to unlock her, you need to go into the «?» room before the boss, catch the right key, and save her.
Abilities: she starts the turn with 1–3 random claws; there is a 30% chance that items will be temporarily improved.





Fiffy Fortuna - to unlock her, you need to get the «Big Luck» achievement.
Makes tokens 10 times more effective, but removes the repeat when choosing rewards.





Thonk - to unlock him, you need to defeat the farthest enemy first in battle.
Take the «Bunny Banni» character — her second claw is a harpoon, which uses items twice. In the earliest battles, catch the «magic wand» item and use it several times until you kill the farthest enemy; do not touch the nearest enemies.





Starlet — to unlock, you need to get 3 dodges at once (use a upgraded knuckles with the «Fussy» perk).
Each turn starts with 1 dodge, damage is reduced by 50%, but you get 1 grace with each attack.

Pearl - You just need to upgrade the pearl in the workshop





Strongman - collect 1,000 Power (quick achievement unlock at the end of this chapter);





Blockmaster - (Quick achievement unlock at the end of this chapter.)
You need to collect 1,000 Block.

To do this:
So take Chief Bunner and three of his Chief Bunner claws to complete all three of the «BlockMaster», «Strongman», and «Critical Hit» achievements in one run. This gives you 200% of your existing shields at the start of every run.






(Quick achievement unlock at the end of this chapter.)
You need to deal 5,000 critical damage in one attack.

To achieve this:
choose the Snow Baroness character;
it’s important to choose Mr. Krull’s claw; the rest is up to you;
apply as much frost as possible to any boss during the run;
find the «Flask with Liquid Nitrogen» item;
upgrade snowballs, icicles, and the flask with liquid nitrogen;
take the Frost luck token to get more frost-related items to drop;
don’t take items that aren’t related to frost — they’ll only get in the way;
instead of shields, take healing items.

WARNING!
You can get the «BlockMaster», «Strongman», and «Critical Hit» achievements at once and very easily!

You’ll need:
the Commander Krullson character;
three of his claws;
the «Eye Patch» and «Energy Drink» items.
Here’s how it works:
After each turn, your shield will automatically double.
First, take a couple of shields and keep doubling them until you reach 1,000 (you can do this in the first battle) — then you’ll get the «Block Master» achievement.
When you find the «Energy Drink» item, accumulate 2,000 shields and use it — then you’ll get the «Strongman» achievement.
Finally, accumulate about 10,000 shields, use the «Eye Patch», and attack any mob — then you’ll get the «Critical Hit» achievement.
Shields accumulate very quickly due to the doubling effect. It took me less than 10 minutes to get these three achievements.

Rescue Mission - To free Krali, you need to reach level 20 and then enter the room with the «?» sign. After that, everything will depend on random chance — you’ll need to catch the right key to open the cage. Each run features a new key.

Hare L Quinn protip: when you pick a key and she doesn't get saved, you can save and quit to menu and return to your save and you can try another key, it's way quicker rather than having to finish new runs







Gambling Luck - You need to win at the slot machine

The achievements that take the longest to get — you have to go through the rounds/attempts with certain conditions


You need to complete a run with 1, 2, or 3 paws. You get paws for reaching level 20 with one of each hero.

The achievement is counted only once. If you haven’t unlocked these three achievements, you won’t be able to complete a run with 3 paws and unlock all of them at once.

IMPORTANT!!! Achievements are counted only after your death in room 21 or highe








Good Fortune - You need to collect all the luck tokens in several runs. You can check your progress in the reference guide.
After unlocking this achievement, you will unlock the character Fiffi Fortuna.




To complete the levels of difficulty 10 and 20 — each level can be completed with any character.



There are many ways to complete the game (you can share your own in the comments).
My build:
Character: Hare L. Quinn;
Paws: 2 — Fran the Nanny and the Trash Collector (up to level 10; after level 10, replace the Trash Collector with Count Clawshankula);
Tokens: pet, strength, poison.

IMPORTANT!

I recommend:
to get the «Credit Card» at the beginning and level it up — at the end, thanks to the pets, it can kill even the final boss with the first attack;
if you realise that the next attack will be the last, you can restart this battle: press «Menu», then «Exit» and save the game;
if you use Kralli Quinn, try to get more advantageous claws at the beginning of the battle — this will make your character virtually invincible.
