Monster DR and weaknesses

Monsters may be resistant to or fully protected from some forms of attack and vulnerable to others.

For reference, "normal" damage is shown with red numbers. Resistances (via DR) are indicated by yellow damage numbers: this means some of your damage is being reduced and it might be possible for you to overcome this by changing weapon type. Full protection is indicated by white zero damage numbers. Some forms of damage are particularly effective against a monster and this is indicated by pink damage numbers.
