Below is a list of the usable flags for immunities, resistances and vulnerabilities a mobile may have on Dawn. Please be sure to check the notes at the bottom of the list.
| A | summon | Summoning and gating magic |

| L | poison | Venoms and toxic vapors |
| M | negative | Life draining attacks and spells, or unholy energies |
| N | holy | Holy or blessed attacks |
| O | energy | Generic magical force (i.e. magic missile) |
| P | mental | Mental attacks (such as a mind flayer's mind blasts) |
| Q | disease | Disease, from the common cold to the black death |
| R | drowning | Watery attacks and suffocation |
| S | light | Light-based attacks, whether blinding or cutting |

Note: Resist the temptation to make "Achilles Heel" style mobiles, that is creatures that are immune (or almost immune) to all but a single attack type. Such mobiles are extremely boring to fight, and ultimately not very hard to defeat. Strive to make a balanced mobile, with no flags that aren't explainable by its nature.
Important Note: the two generic categories (weapon and magic) are merged with more specific flags, so that a mobile which is (for example) immune to magic but vulnerable to fire will take normal damage from fire. Example: a fire demon might be immune to fire and negative energy (HM), resistant to mental attacks and weapons (DP), and vulnerable to holy attacks as well as cold (IN).
