Defeat the Kraken!
THIS ACHIEVEMENT WILL STILL UNLOCK IF YOU DEFEAT THE KRAKEN ON APPRENTICE MODE!
(I have received mixed reports after updates have been released that it still unlocks on Apprentice and also that it does not. Please continue to post feedback on if it unlocks for you on Apprentice mode)
Once you have unlocked enough cards to face the Kraken, be ready for a fight. Try to gear up with a nice armor and weapon. You will also be fighting Lizardmen so an item like Herne's Antlers would help a lot.
The fight will follow a general outline:
1. Lizardmen will spawn.
2. The Kraken will electrify a platform. Avoid that platform until it is safe.
3. The Kraken will slap a tentacle down onto the ship. At this point in the cycle, it is best to roll around and stay away from the Kraken head to avoid getting hit. Once the tentacle is down, attack the tip to destroy the claw.
4. The Kraken head will float close to the boat. Take this opportunity to hit the head as many times as you can. If you dont attack it enough, it will spew fire. If you are busy with the Lizardmen and it spews fire, stay to the opposite side of the boat.
A few tips:
-Play on apprentice (easy) difficulty.
-If you heavily damage the Kraken head each round, the outline should only cycle 3-4 times before you win.
-Be ready to fight Lizardmen bosses like the Prince, Queen, and/or King.
-The Time Heals artefact is always one of the best things to have when facing a boss.
***Warning for completionists: This can be obtained without purchase of the Wildcards DLC. There are a few achievements that are obtainable and unlock from a "Title Update" DLC. If you want to avoid unlocking any Title Update achievements when playing the base game, Only play on normal difficulty, and do not complete any cards related to the Kraken or Elder Lizard. The dev has included some DLC encounter cards in the main game and they can be identified easiest by a maroon/red tab in the top right corner of the card with a gold monster head symbol.***
