Monster attacks

Original by The Sheep

It is important for a roguelike to have monsters that are distinct -- they should vary more than health and name. Giving monsters (and the player) diverse attacks is one way to add variety to your roguelike.

Because of the loose organization of this list and its inclusion of more general "things monsters could do" that are not attacks, such as flying, R. Dan Henry created a more systematic list of monster attacks in a structured list.

The following is a list of monster attacks and effects.

Methods

• Hit -- "Bump into the monster and hit them with your weapon".
• Shoot -- Standard ranged attack. The player selects a target or shoots in a given direction.
• Beam or Ray -- Shoot a beam that affects all in its path. Some beams/rays may be reflected.
• Area attacks -- Attacks that affect a certain area. Examples include:
  • Fireballs and other basic spells cause damage over an area.
  • Noxious (or hallucinogenic, blinding) gas that dissipates over time.
  • Earthquake. May stun, damage, or cause debris to fall.
• Disease -- Spreads its effects when the monsters/player are near, or when something diseased is touched, worn, or eaten.
• Play music -- Use an instrument to play music that has some effect on all that hear it.

Bodily weapons such as:

• Claws, hooves, horns, tails.
• Quills and spikes (in defense, or shooting them in some way).
• Breath attacks (breathe out poison or a beam of flame).
• Gaze attacks (typically paralyzation or stoning, as with Basilisks or Medusa).

Effects

Any given effect may be permanent or temporary. There may be an onset period ("you feel your limbs stiffening") where you may act to prevent that effect. You may guard yourself in various ways against certain effects (cold resistance, unchanging).

Basic

• Wound -- Create a wound with long-term effect, i.e. bleeding.
• Poison, Sickness -- A stat of the player may decrease (perhaps temporarily).
