Grass terrain, rendered as a green period or comma. It could have the following properties:

• Dies and turns to normal floor if hit by fire or have a death ray zapped over it.
• Turns into fire terrain if hit by fire and can spread to nearby grass.
• You can plant trees on them, whereas you cannot do this on normal floor.
• Small monsters that are capable of hiding under objects can hide in grass.

Amulet versus magic, which gives magic resistance when worn but also makes it difficult for the wearer to use magic, translating to a sharp penalty in spellcasting rates and, depending on the implementation, reducing or nullifying the effects of magic items.

Giantslayer gets its bonuses against any monster that is larger than you, rather than just giants specifically. (Possibly it still gets bonuses against giants specifically even if you are as big as one.)

Note that dNetHack has a similar feature in which Giantslayer gets bonuses against any monster that’s Huge or Gigantic. It’s also been suggested to drop that to any monster of size Large or larger.

Crossbows deal more damage than bows, but the multishot bonus is lower because they are slower to reload.

Note a similar implementation in dNetHack, where crossbows always only shoot one bolt but the multishot amount multiplies the damage of that bolt.

Shepherds’ crooks: a wooden multi-purpose weapon-tool.

• Damage is a little less than a quarterstaff. Should probably not weigh as much as a quarterstaff; it would be hard to justify 40 weight any way you slice it.
• Can be applied to give a menu offering to do one of three things (and unlike grappling hooks it never does the wrong thing):
  1. Hit a monster at polearm range (skill-dependent).
  2. Attempt to hook a monster at polearm range. Tame monsters are always hooked. Peacefuls are always hooked, but may be angered. Hostiles might be hit instead of hooked. If the monster is hooked, it will be pulled towards you, or you will be pulled towards it if it’s much larger than you.
  3. Grab the top item from a square, even if the square is a trap or water square.
• Wielding one passively gives a boost to the radius in which pets will follow when you change levels.
• Wielding one also makes pets follow you as if you had a treat.
• Can be applied to a monster two squares away to yank it towards you, which may stun the monster.
• Binders in dNetHack could start with one. Peasants in dNetHack could generate with them.
• Two-weaponing a crook and a flail should do ‘‘something’’ (from Egyptian pharaoh iconography).

Limit the amount of tamed monsters you can have at once.
