The Outcast Collection Agent

 refers to an unmarked and repeatable quest in Fallout 3.

You can trade certain pieces of power armor (Power Armor marked only as "Power Armor" or Enclave Power Armor; you cannot trade Brotherhood Armor), some energy weapons, sensor modules, and scrap metal to Protector Casdin at Fort Independence. In return he will give you your choice of the following, in quantities according to the perceived value of the item:


 * 5.56mm ammunition
 * Frag grenades
 * Rad Away
 * Stimpaks

Once the Lone Wanderer has gained 50 "points" (see table below), they are told that they are considered friendly by the Outcasts. This allows for infiltration of Fort Independence without encountering the hostility of the residents (see Getting In). Casdin also stops confiscating any Outcast Power Armor that the player has.

Value Table
The following 'base value' table assumes the items are in full repair. 1Scrap Metal must be traded in groups of two; Alien Power Cells must be traded in groups of twelve.

2Casdin will not take Tesla Helmets

Collecting for Caps?
You can make a profit from Casdin by re-selling the items you trade him for. But is it worth it? First, here are the items you can receive, and their value:


 * Stimpaks at base value of 25
 * Frag Grenades, value 25
 * Rad Aways, value 20
 * 12 5.56mm Rounds, value 12 (12x1)

As you can see on the Value Table, in any one deal, you can receive an equal number of one of these: Stimpaks, Frag Grenades, or Rad Away. Or, you can receive a higher number of 5.56mm bullets. For the items besides the bullets, the Stimpaks and Frags are worth more than the Rad Away, so the Stimpaks pretty much win out of these three on a purely profit basis - they're weightless.

The 5.56mm rounds do not scale the same as the other three items. As the number of reward points increase, the better the ratio of bullets to the other rewards. For example, there's a 12:1 ratio at 1 point, but a 24.2:1 ratio (484/20) at 10 points. However, if you compare the value of Rounds to the value of Stimpaks for any given item, Stimpaks always win. At the low end, you get 2.083 times the value (Sensor Module: 1 Stimpak = Value 25 vs. 12 bullets = Value 12). At the high end, Stimpaks still (barely) win at 1.033 the value (Alien Blaster: 20 Stimpaks = 500 vs. 484 bullets). So, Stimpaks (or Frags) are always the best reward, on a pure profit basis.

If items you collect are in very good Repair, almost none are profitable to "launder" through Casdin. (Barter skill doesn't matter here, because both the original item and the reward are usually subject to barter, even though Casdin isn't.) The only things that at least break even when at 100% repair are:
 * Alien Power Cells (Base Value: 120 for 12), which will show a 2.3x return (275 for 11 Stimpaks) - but these cells are few and far between, and priceless if you want to use alien weapons
 * The Alien Blaster (full Value 500) itself just breaks even (20 Stimpaks) at 100% repair... but it's extremely rare and valuable, plus, who'd repair it with the Firelance, anyway?
 * Finally, 2 Scrap Metals are worth 20 (with Walter's Scrap Metal quest), but get you a Stimpak worth 25. In this one case alone, your Barter skill must be very high (&gt;80), because Walter's 20 caps are not subject to barter, while selling Stimpak rewards is.

Conversely, if items are in bad repair, Casdin still gives his full reward. This makes them worth considering. For example, if degraded to 25% of their full value: However, So weapons need to be in really bad shape to make a profit via Casdin - Plasma weapons should be less than ~20% repair, and Laser weapons should be less than ~10%.
 * You'd make 4x profit on the Alien Blaster at 25% repair (value 125 vs. 500 for Stimpaks), but again, you'd probably not do it. (Unless pickpocketing Casdin - but that's an entirely different story.)
 * Enclave and regular Power Helmets (base value 110; 25% value 28) will make a 2.7x profit (3 Stimpaks = 75)
 * Tesla Power Armor makes 1.6x profit and Enclave Power Armor makes 1.4x when at 25%
 * Regular Power Armor only makes 1.2x when at 25%
 * The Plasma Pistol and Plasma Rifle only get ~.76x (you lose money), and
 * The Laser Pistol and Laser Rifle only get ~.52x (you lose half your money), at 25%.

The Sensor Module is always a bad deal, on a pure profit basis - you're cashing in something worth 30, for something worth 25 at best. But they can be accumulated earlier than the other items to meet the point requirement for getting into Fort Independence, in exchange for grenades or ammo that exist in limited supplies at low level. The 250 cap loss (50*(30-25)) is a small price to pay for early access to the Outcast's interior. Still, Sensor Modules are also an important component of Bottlecap Mines, which are probably the best early money makers from schematics, and take 373 damage per mine. Maybe Scrap Metal is better for Getting Into Fort Independence early.

If you have The Pitt, things are a little different and a lot more convoluted. Trading for the 5.56 ammo starts making sense, as the Ammo Press can convert the 5.56 into other ammo types. Converting the 5.56 into 5mm at a 1:3 ratio makes it the most profitable (although long-winded) path. For example, converting a low quality Laser Rifle into 96 5.56mm ammo with Casdin, then into 288 5mm ammo at the ammo press will allow the player to then sell them at about 0.6 bottlecaps per round (with middling charisma / barter) or about 170 bottlecaps. As a low repair laser rifle can be bought in some shops for about 50 bottlecaps, the rate of return is decent.

In summary, is it worth funneling items through Casdin to generate caps? Yes, you can make money - but it's probably not worth all the hassle.

Still, you can use the math to see which items are best for getting in to Fort Independence cheaply and/or early:
 * Scrap Metal, particularly if your Barter is high (but you'll need 100! that's 1000 caps Walter's not giving you)
 * Sensor Modules, if you want to get into Ft. Independence quick and aren't worried about Bottlecap Mines
 * If your Barter is low, give banged-up Power Helmets or Power Armor, or really banged up Plasma weapons, or practically dead Laser weapons.
 * You can purchase low condition laser weapons from various vendors and make a profit:
 * Flak and Shrapnel in Rivet City normally stock 2 low quality Laser Pistols at 25 caps each (With 10% Rivet City Merchant's discount). One laser pistol is worth 2 Stimpacks, which at a price of 66 for 2 from vendors, is a great profit.
 * Tulip in the Underworld sells two low condition Laser Rifles at 52 caps each. Laser Rifles are worth 4 points which is 5 Stimpacks, 5 Radaway, 5 grenades or 96 5.56 ammo. This is a great way to make profit.
 * A great way to make money is to collect a large amount of Scrap Metal (50 - 100) and give it to Casdin, then pickpocket it back. You can collect as much 5.56 ammo or as many Stimpacks as you like (if you can stand clicking through the dialogue for that long), you'll gain enough points to be trusted by the Outcasts, and you can then go give your Scrap Metal to Walter after wards to negate the karma loss due to the pickpocketing.

Bugs

 * Sometimes Protector Casdin can be found Dead. On the PC, this can be fixed by using the console commands:, ,
 * There is a risk that Casdin can disappear after a battle with a local spawn if it takes him too far from Ft. Independence (such as on top of the hill/bridge in front of the fort).
 * There is no option to give Casdin a Tesla Helmet.
 * You also cannot give him a Gatling Laser, though this may be due to its classification as a big gun. It may be also that a majority of Brotherhood Outcasts already possess Gatling Lasers.
 * If you give him the Alien Blaster, pickpocket him, or kill him and take it off his corpse, its condition will be restored to 100. If you pickpocket rather than kill him, this can be repeated for numerous rewards and repairs. However there is a chance he will equip the Alien Blaster in which case getting it back can be quite the hassle.
 * If you paralyze Casdin using the Paralyzing Palm and try to take the Alien Blaster from his body while he still has it equipped, it will likely crash your game (Confirmed on the PS3). Remove the Blaster ammo first then exit and re-enter his inventory so he equips back to his default Ripper before trying to take the Alien Blaster.
 * Occasionally, Casdin won't accept Power Armor of any kind. (unconfirmed)
 * Sometimes Casdin will not accept Enclave Power Armor then he will and then he wont and then he will ETC. (the same happens with Tesla Armor) there doesn"t seem to be any fix for this or cause.
 * Casdin won't accept Brotherhood Outcast Power Armor or its Helmet.
 * With preserved cryo grenades from the mothership zeta add-on all of the items you gave to Casdin can all be obtained back by throwing one at him which you can take off a bit of Casdin's health to freeze him then quickly take back all of your items and reuse them to gain a massive amount of ammo and this does not make all outcasts go hostile unless killed by a critical hit plus attempts can be made to remake an old glitch called the S.M.G (scrap metal glitch).
