Diethon

Toxicrotale · no. 101 in the monster list
Everything is read from the game's code, unless stated otherwise

These sickening snakes are immune to poison, can vomit up a Venom Mist, and will run at the sight of superior strength.

Superstition says to take three steps back and set off somewhere else if a diethon crosses your path at night.

Items

Habitat (in-game monster list)

The Plumbed Depths · Western Coffinwell

In the game, a defeated monster's entry names one of these places as soon as you have visited it, even if you never defeated that monster there; otherwise “?????????” (checked in game). The first two are named, “Etc.” for the third.

In the field

Behaviour: spots the party all around it up to 3.5 units, then chases it, but runs away if the leader's attack + defence exceed 3 times its own.

In each cell: share of the visible monsters in that zone, then (in brackets) share of that zone's battles it takes part in, alone or with others. “Joins”: never visible, it only comes along with the monster you touched. “In the forest”, “on the coast”…: which monsters appear depends on the ground under the hero's feet (grass, forest, coast, rocky ground, swamp…); with no detail, they appear anywhere on the map. “Starflight Express stop”, “islet”, “part”: a separate corner of the region, reached as shown. Exact figures from the game code.
