Sebastian Klein

This'll probably get merged into the NetHack: The Next Generation article whenever I rewrite that.

Sebastian Klein is the creator of NetHack: The Next Generation, a NetHack 3.1.3 variant which he released in 1994. Very little information is known about him - he has a personal site found here, and posts from Klein can be found in rec.games.roguelike.nethack as late as 2000.

Doppelganger (starting race)

Strategy

Remember that the minimum required XL is the experience level at which the form would have the same check as a controlled #youpoly attempt, e.g. there is always a set ¹⁄₂₀ of feeling like a new doppelganger rather than achieving the desired polyform.

Common polyform traits

• The various medium-sized humanoids can wear all available armor and use weapons.
• Demons have natural fire resistance and poison resistance, and bare-handed melee attacks can gate in other demons. However, they are weak to silver and blessed weapons, you cannot pray as a demon, and tame demons are usually traitorous, making them dangerous to keep around if they have more HP than you.
• Vampiric monsters are inediate and usually possess intrinsic regeneration and breathlessness - most of them are medium-sized humanoids, and they can feed and increase nutrition through their bite attacks. However, many of them are also weak to silver and blessed weapons and/or cannot access prayer due to being undead.

Monsters to review

Before gaining polymorph control

• Medium-sized humanoids can wear all armor and use weapons.
  • Human mummies are inediate and normal speed, although not guaranteed until level 6. They make a good form if you want to wait around an altar and sacrifice. Human mummies have greater carrying capacity than their elven counterparts, and are available at the same level.
  • Salamanders (guaranteed at level 8) are humanoid with good AC and speed, and have 2 weapon attacks, a fire touch, and a fire crushing attack.
  • Doppelgangers can start polymorphing into mind flayers with a reasonable chance of success at level 6 or 7; the brain-eating attack will make short work of most monsters, but is useless against those without heads or brains, and downright dangerous against monsters with passive attacks. Mind flayers will not be stoned when attacking a cockatrice; the tentacle attack is instead turned off.
• Demons
  • Chasmes are guaranteed at level 8, and attack quickly with 4 hit die that can put foes to sleep. Great for killing shopkeepers (though this will come at the cost of -5 alignment record if you kill the shopkeeper without having them become angry with you due to not waking up).
  • Mariliths, guaranteed at 7, have normal speed, decent base AC, and attack 5 times. The multiple attack makes demon gating very effective.
• Although not guaranteed until level 8, a level 5-7 character has a reasonable chance of polymorphing into a basilisk. They are essentially stronger cockatrices, with the same passive attacks. As such, they can be very handy for getting through the Gnomish mines. Nutrition can be a problem since you can't eat statues. Also, the similar asphynx may look appealing, being faster, but it can carry very few items, and cannot pick any up at all.
  • If you're trapped by a single monster, chickatrices are guaranteed at 4 and will stone an attacking monster. However, they have extremely low base HP, can carry very little, and are slow, so they should only be used as an instakill in case of emergency.
• Unicorns are guaranteed at level 4. They have high speed and a decent attack, and can use #monster to remove some bad effects.
• Mumakil are guaranteed at level 5. They have comparatively very strong attacks, but somewhat low speed. Especially good if you are fast or, better still, very fast.
• Leocrottas are guaranteed at level 6. They are moderately fast and quite powerful, although unable to use any weapons or armor.
• Oviparous monsters can provide some highly useful pets via egg laying, especially in the early game:
  • Gargoyles and winged gargoyles can sit and lay eggs that will hatch has gargoyles; normal gargoyles can wear armor, but the flying winged gargoyles cannot. Both forms also have excellent natural AC.
  • Soldier ants are guaranteed at level 3, and as pets, can if anything be almost too effective - they can often close in, kill and devour weak foes in the time taken for an unhasted player to make even a single move. Creating an army may be tempting, but this can lead to nutrition problems if you can't reach corpses in time. Spawning 2 or 3 is generally more than sufficient.
