Last month of spring in Ancardia. In every new game of ADOM the player character arrives at Drakalor Chain in Unicorn.

Harder to corrupt by Chaos effects, hard to change to a different alignment once lawful, +2 to initial Appearance
Bonus evaluation Edit
Harder to corrupt by Chaos effectsEdit
Various tests and data seem to indicate that this effect decreases corruption gained by 10% rounded down and works only if the PC is lawful. Due to the way background corruption works, rounding practically removes any potential reduction on all levels except Emperor Moloch's lair and Chaos plane. Unicorn is much more useful against one-time corruption gains, such as monsters' corrupting attacks, using chaos orbs and eating corpses of ChAoS creatures.
Unicorn bonus stacks with other corruption-reducing sources, such as extreme lawful alignment (L+), and various class powers. Test results for Chaos Orb usage show that equipping elemental gauntlets, having L+ alignment and being born under Unicorn star sign give the cumulative corruption reduction of approximately 70%.
Hard to change to a different alignment once lawfulEdit
+2 to initial AppearanceEdit
Appearance slightly reduces shop prices for female characters as well as has an impact on Smithing skill price when learning from Glod. Apart from these rather insignificant effects, Appearance is involved in resisting corruption, therefore making this particular bonus of mild importance.
This star sign seems to be designed for characters aspiring to be lawful champions and possibly those attempting an ultra ending. It should be noted, however, that corruption-reducing effects of lawful alignment are more than enough to complete an ultra ending (and, obviously a normal ending), eliminating the overall advantage of all star sign bonuses. Therefore Unicorn is (rather counter-intuitively) slightly more suited for chaotic players which have significantly more problems with corruption.
