Angelskin Armor for Starfinder First Edition (Patreon)

Starfinder First Edition specifically assumes that special materials like mithral are already used in armor construction to the greatest degree possible in each suit, so there's no need for special mithral rules such as exist in the feudal fantasy version of the game.

It's a good claim. I was part of the design team that decided that was the way to go.

But it's not... fun. At least, it's not ONE kind of fun. Some people adore having options, including fantasy terms having game mechanical effects in science-fantasy games. And, I admit, I am one of those people.

Now, this is not the route for all games nor is having rules for everything the only way to create this effect. But for people who DO enjoy a big bag of Salty Rules Crunch...

Links to all my Starfinder special materials for armor articles (which is TEN, at time of writing) can be found, along with links to many other Starfinder entries, at the Paying-Patreon Exclusive Starfinder First Edition Index.

Special Armor Material: Angelskin

Though it is a vile, disgusting, clearly abhorrent act, it is possible to use the tanned and treated skin of good-aligned sapient celestials as the primary construction material for light armor. Angelskin is not sturdy enough to be used in heavy armor, and reinforcing enough that it can be dilutes the angelskin so much it no longer grants any of the normal effects of using this leather made from thinking, feeling outsiders.

Price is increased by +20%. However, in many places this material is unavailable at any price, and owning, buying, selling, or making it is illegal. In those societies where celestials are reviled, or corpses are seen as having no special link to the entities they were when alive, it's still rare as its utility is limited. But when easily found, the price of angelskin armor is only a little more than typical armor.

Hardness and hp are calculated as if it was one item level lower (minimum item level 1). Crafting it requires appropriate skill ranks equal to the armor's item level +2 and, if done knowingly, is an evil act.

When a creature with a nongood social alignment (lawful neutral, chaotic neutral, true neutral, lawful evil, chaotic evil, or neutral evil) wearing angelskin armor is hit by a spell or effect that affects creatures not of good alignment differently than those of good alignment, there is a 50% chance the target is affected in the most favorable way between its true alignment and an alignment with a good social element (lawful good, chaotic good, neutral good) closest to the creature's true alignment. A creature wearing angelskin armor that has DR of x/good is treated as the DR being x/--.

Creatures in angelskin armor gain a +2 bonus to Bluff checks to convince creatures they are upstanding and morale... as long as the targets are not aware of the nature of the armor.
