Enclave Hellfire Armor

Enclave Hellfire armor is a heat-resistant power armor worn by high level Enclave soldiers and the specialized, elite Enclave Hellfire troopers. It is added with the Broken Steel add-on for Fallout 3.

Characteristics
This armor is equal to the T-51b power armor (but not the Winterized Version included in the Operation: Anchorage add-on) in terms of DR, item HP, and weight. It does, however, offer inferior radiation resistance, as well as -1 Charisma for the Hellfire helmet as opposed to the T-51b power helmet which has +1 Charisma. The armor's advantage is the +35 Fire resistance, and a +1 Strength stat it also provides.

In contrast to the T-51b which is limited to merchant repair, the Enclave Hellfire armor can be repaired with other sets of Hellfire armor. This advantage alone may make it the better choice among the game's several power armors. That should not be taken for granted, however, as Hellfire troopers are still an uncommon enemy.

The armor is far less stylized than other Enclave armors, and can, at longer distances, be mistaken for T-45d power armor. This can lead to unexpected run-ins with powerful troops, so be cautious if you can't see tick marks for non-player characters.

Bugs
If you have a set of Hellfire armor equipped at 100% condition, and another set of Hellfire armor at any condition is in your inventory, the inventory armor will degrade instead of the equipped armor. This effect also applies to the Hellfire helmet, although as it is considerably weaker you may need more spare helmets to keep a good DR. There is a similar effect with the Tesla armor.

If one drops a stack of the Hellfire armor, or Hellfire helmet (meaning 6+ sets with the exact same damage taken), and leaves it on the ground with no other dropped items, and leaves for an (in-game) day or two, then comes back, all of the armor/helmet pieces will be at 100% durability.
