Evil spirit

The Evil spirit is the boss in Rum Deal. It only attacks with Melee, so turning on Protect from Melee is sufficient in protecting a player from most damage. High-levelled players should not worry about this battle, as the spirit is rather weak, has no weakness, and has few hitpoints for its level.

A two-handed weapon can kill him relatively quickly. Poison is not necessary, as the spirit is immune to its effects. If a player is above level 40 and uses Protect from Melee, there is little need for food. He can only be fought once.

Trivia
The 'pun intended' comment on his examine text is a reference to a spirit, which is a type of alcohol and Braindeath rum, which is an evil alcohol.
