Some monsters are considered kebabable. This gives you +2 to-hit when attacking them using any weapon using the spear skill.[1]

The following monster classes are kebabable:[2]

X xorn

xorn D dragon

dragon J jabberwock

jabberwock N naga

naga H giant humanoid

Strategy

This feature is marginal even for spear-using classes. The only significant use of this effect would be to use naga hatchlings as an opportunity for the training of the spear skill from unskilled to basic.

By the time you face any other kebabable monster you are usually at such a level that hitting is unlikely to be a problem even at unskilled.

History

In versions prior to NetHack 3.6.0, weapons using the javelin skill also received the bonus. The skill has since been merged into the spear skill.
