How to unlock the Guildean Knight achievement in Chasm - Definitive Guide
Timmah200
You have to select the difficulty at the start of a new save file and it cannot be changed afterwards.
Complete the game on hard difficulty to unlock this trophy. Enemies take more hits to kill and deal more damage to you, so tread carefully! Finding Dom, Narina, and Ash will help you because they will craft weapons and sell you spells/potions. Finding the high tonic and high potion recipe for Ash will help with the Magma Chamber and final boss. Defeating the Bone Worm and Titan bosses without getting hit will reward you with items that make hard difficulty a lot easier. See Prizefighter

-The worm is pelted with axes. will give out armor that gives good protection and a small chance to nullify damage.
-Titnan always has the same pattern in battle, so all you have to do is memorize his attacks (or watch them on YouTube). Gives you a titanium hammer that creates a wave when it hits the ground, which is extremely useful when passing through the next location and arena.
-It’s better to throw magic at the king and hit him with a wave from the hammer, dodging attacks by jumping from the wall. Gives one of the best swords in terms of damage, hitting vertically (I ended the walkthrough with it)
I also advise you to find a recipe for slowing down time and stock up on 4-5 pieces. The last 2 bosses won't be a problem with them.
