• Lich, the Fiend of Earth is a unique lich with powerful spells. They are probably the weakest, and yet unlock one of the most helpful artifacts in the quest - the Earth Crystal, which grants slotless 1/2 physical damage.
• Kary, the Fiend of Fire is a unique marilith with spells, a crushing hug attack, and six incredibly damaging weapon attacks per turn - she uses giant scimitars dealing 1d18 damage. She is probably the most lethal of the Fiends, and even more so to characters vulnerable to iron. Defeating her unlocks the Fire Crystal, which grants slotless fire resistance.
• Kraken, the Fiend of Water is a unique kraken with spells, more physical attacks, and a blinding spit. They are not particularly dangerous to the average character who has made it past Kary, but the drowning attack is of course a threat. Defeating them unlocks the Water Crystal, which grants slotless cold resistance.
• Tiamat, the Fiend of Wind is a unique dragon with spellcasting attacks. She likes to cast the Plague spell at you, inflicting you with sickness, so keep an eye on your status line. She is not particularly threatening, but the retriever on her level can be. It is covetous, resistant to elements as well as slashing and piercing weapons, and teleports you around the level. The average character may not have a means of dealing with it, so avoid going near it - it spawns in the bottom right of the level, and the exit is to the top right. Defeating Tiamat unlocks the Air Crystal, which grants slotless shock resistance.
• Chaos is the final boss of this branch. He is incredibly threatening with almost 2000 HP, powerful spells (including summoning spells), and is covetous. A combination of Elbereth and pentagram wards (or a better ward against major demons if you have one) burnt or engraved on the upstair can be a great help. Defeating Chaos unlocks the Black Crystal, which grants slotless magic resistance.
