There are some items in the game that have some strange levels of availability, in some cases these items are either much rarer than they should be or are more common than the lore would suggest.
For example the Inferno Pistol is listed as Extremely Rare, but by lore (and its own description) there are ‘maybe’ a handful in an entire sector of space and are generally found in the hands of Inquisitors, Very-High ranking Adeptus Mechanicus, and some of greatest heroes of the Adeptus Sororitas. By all accounts this weapon is so rare that it really should have an availability of Near Unique.
In fact its so absurdly rare that it shouldn’t even be listed in the armoury (any more than a Daemonhammer or Railrifle), it just doesn’t make sense for Guardsman to have such a weapon.
In comparison the Force Weapons are far more common than the Inferno Pistols, found in the hands of many psykers across the Imperium (including those of under the Guard), is set at Near Unique but should be Extremely Rare. To writ a Player taking the Sanctioned Psyker specialization will eventually want a Force Weapon, for one reason or another, but with a “Near Unique” availability they have almost Zero chance to ever get one (baring GM fiat); yet they stand a better chance of getting the (in lore) much rarer Inferno Pistol.
In fact its so over-the-top rare that is doubtable that ‘any’ Sanctioned Psyker in the Imperial Guard actually has one.
Another item of bizarre rarity is, surprisingly, the Survival Suit.
This one actually avoided my sight for a moment until I remembered the Table 2-6 in the Regiment Creation Chapter, at which point I look back and realized it strangeness. The chart page 34 has the Survival Suite placed at 3 points, or Plentiful Availability, yet the armoury has the same item as Very Rare. Obliviously one of these is wrong.
Has anyone else found items that are either too Rare or too Common for what ‘should’ of been?
And just throwing this question out there as well: Do you see much point in having items over Extremely Rare listed in the Armoury? Or do you think the items are just there to troll Players? (I‘m looking at you Omni-Scope!!!)
