Let's Play Eternal Dread 2 Part 7: Fighting Kwanpiz
1In this video, Alyssa goes through Kwanpiz's Fortress and fights Kwanpiz herself who was a very strong opponent. She manages to defeat her, but she's too late as the new Demon Lord has been summoned. She reports back to Floria who tells her to head to the Arid Wasteland to meet Carla. At the camp, she encounters Bianca and Riel with the former talking about a Re-Status Ritual (which you can use in Eternal Dread to reset Riel's stats). After the conversation, Alyssa tries out the optional Trial of Agility, scoring 150.
I consider Kwanpiz to be the hardest boss because she inflicts Poison which lowers your health, uses webbing to immobilize you, Pain to inflict Poison, Confusion, and Silence, and can use Earthquake which is very lethal to characters (it can easily kill Alyssa even at max health). I remember dying to her several times mostly because of Earthquake. However, I managed to defeat her on my first try in this video.
