Astral corsairs are adventurers who live by their skills, sailing around the astral void. They have a range of specialised astral-sailing and adventuring skills unavailable to other characters. However, corsairs are not always to be trusted.

### Boarding
Corsairs who are in the act of boarding another vessel don't suffer the usual boarding penalty to attack rolls and Armour Class.
### Combat
Because of their need for free movement in the open astral void, corsairs cannot wear armour heavier than leather and cannot use shields. They can use any weapon.
### Astral Corsair Skills
Corsairs can use the following skills, with the chance of success shown below:
- **Climb sheer surfaces (CS)**: A roll is required for each 100’ to be climbed. If the roll fails, the corsair falls at the halfway point, suffering falling damage.
- **Move silently (MS)**: An astral corsair may attempt to sneak past enemies unnoticed.
- **Astral-faring (AF)**: An astral corsair always knows which way is down, how to get by in the open astral void, and how to make repairs when their vessel takes on damage.
- **Tightrope walking (TW)**: Corsairs can walk along tightropes, narrow beams, and ledges at up to half their normal movement rate. A roll is required every 60’. Failure indicates that the corsair falls and suffers falling damage. Windy conditions may reduce the chance of success by up to 20%.

[Astral Corsair Skills Chance of Success]
### Rolling Skill Checks
All skills are rolled on d%, with a result of less than or equal to the listed percentage indicating success.
#### Player Knowledge
The referee should roll for hide in shadows and move silently on the player’s behalf, as the corsair does not immediately know if the attempt was successful. If a hide in shadows or move silently roll fails, the referee knows that the corsair has been noticed and should determine enemies’ actions appropriately.
### Lore
From 3rd level, a corsair has a 2-in-6 chance of knowing lore pertaining to creatures, magic items, or heroes of astral-plane-related folktale or legend. This ability may be used to identify the nature and powers of astral-related magic items.
### Sneak Attack
When attacking an unaware opponent from behind, a corsair receives a +4 bonus to hit and doubles any damage dealt.
### After Reaching 9th Level
A corsair can establish a crew, attracting 2d6 astral sailors of 1st level. These corsairs will serve the character with some reliability, and may be used to run one or more ships.
