Enemy Damage Type Multipliers

Every enemy in the game has a couple of lists of damage types and different things that they do to them. The things that happen to these damage types happen to the incoming damage of this type alone and do not apply to any other damage types that may be included in the same attack.

Ignored Damage Types
Commonly reffered to as the "Armor Ignoring" damage types, these are the damage types that are ignored when armor is applied to incoming damage. There are currently only four types of damage that make an appearence in this list: These four damage types show up on the Ignore Damage Types list for all enemies that have Protected Body Parts, the only exceptions being the absense of Physics Impact on the Grineer Commander, Seeker, and Roller.
 * Armor Piercing (i.e.: Snipetron, Despair,  Piercing Hit)
 * Physics Impact (i.e.: Boltor, Kunai, Paris)
 * Poison (i.e.: Torid, Acrid, Mire)
 * Serrated Blade (i.e.: Most (but not all) mele charge attacks, and the Lanka...).

If DE would add faction specific damage types to this list (ie: fire for infested, electric for corpus), it would actually fix a lot of scaling issues for abilities, but I digress.

Damage Type Multipliers
The other damage type related list that enemies have is the damage type specific multipliers. This list include the damage type, body part affected, and the flat multiplier to this damage type. In general, damage types will be multiplied the same accross the entire body, but in some cases, such as the Corpus Crewman and Bullet damage, the multiplier only takes effect to headshot damage.
