How to unlock the Hawk Eye achievement in Death's Door - Definitive Guide
This can be unlocked only after acquiring all four spells and heading towards a cob-webbed blocked door near the Lost Cemetary door. You will have to defeat a mini-boss through the upgrade door, which will give you the upgraded arrow spell which allows you to charge your arrow for more damage!
