Mindless. This creature is immune to mind-affecting magic. Mindless creatures make saving throws as if they were half of their listed hit dice with the exception of poison or death magic saves. The creature will use tactics instinctively, normally attacking the nearest opponent (or if several, one picked at random). Unless attacked by more than one opponent, it then attacks the same creature until it's prey drops—then it uses one round of coup de grace attacks before beginning to consume it (unless the description notes a different behavior). Otherwise, a mindless creature will attack the same opponent until it is damaged in melee by another opponent. The creature will then attack the opponent that last damaged it until it drops as noted above. Mindless creatures will only attack those not in melee unless all creatures in melee have dropped and are not moving. If a mindless creature has a special attack not related to it's melee weapons, it will use that attack if it rolls under 51% in any new round unless the description of the creature notes otherwise. Area attacks will target melee range creatures first and any creatures outside of melee range will be incidental (simplest placement to hit melee combatants or, if necessary, random placement of the ability). Some mindless creatures will have a preference in terms of prey (for example, attacking smaller creatures first) and this must be assessed when determining the creature's actions. Mindless creatures do not use regular rules for morale. A mindless creature always has a flat 50% for morale and begins checking for morale once it has reached under 50% of its hit points in damage unless the description states otherwise. A mindless creature cannot communicate with creatures not of it's type (and even then only at a very basic level; e.g. Threat Perceived, Food, etc.), has no languages, and has an Intelligence Rating of "Non-" (effectively "0").
Slow. A zombie always takes a 1d6+3 segment delay in combat.
Undead Traits. Undead are immune to the following spells or effects: ageing, charm, command, ESP, fear, hypnotism, paralyzation, poison, scare, sleep, and suggestion. All aligned undead radiate evil that may be detected (the degree of which is normally a function of their hit dice, although there are exceptions).
Vulnerability to Holy Water. Zombies take 2d4 damage from a direct hit with holy water (normally damage would be 1d6+1).
