[Warlocks](Corvanis%20Warlock.md) gain [Exposure](Exposure.md) as normal when casting magic, however, they can choose to [Hide (C)](References/Terms/Actions/Hide%20(C).md) it from being observed. When they do they can hide an amount of [Exposure](Exposure.md) equal to their class level. [Exposure](Exposure.md) that is hidden cannot benefit the [Corvanis Warlock](Corvanis%20Warlock.md). While hidden, only opposed rolls and effects that reveal [Exposure](Exposure.md) can reveal it on the [Corvanis Warlock](Corvanis%20Warlock.md).
A [Corvanis Warlock](Corvanis%20Warlock.md) who possess’ permanent [Exposure](Exposure.md) from their race naturally hide this [Exposure](Exposure.md) and does not need to calculate it when determining [Exposure](Exposure.md) to hide.
[Warlocks](Corvanis%20Warlock.md) pay a price for this, as they only ever have two spell slots, these are always cast at the highest spell level possible for the [Corvanis Warlock](Corvanis%20Warlock.md) to cast by the [Magic (C)](Magic%20(C).md) role’s scaling.
[Warlocks](Corvanis%20Warlock.md) start with the [Eldritch Blast](Eldritch%20Blast.md) [Cantrip](Cantrip.md).
