Void Walker. Trading the ability to learn the inherent spells of a ranger, you learn how to use the void to displace your very being. Taking the dash action now causes creature's to lose track of you, almost as if you're teleporting to a new location, causing your being to become nothing for a brief moment of time.

Void Speech. Your connection to the void allows you to corrupt any object or creature of your choice and allows you to converse with them for 10 minutes regardless of languages known. The void's corruption will then corrode them away, destroying an object without imbued magical properties or dealing 1d4 damage to a targeted creature.  You can also choose a single memory of your choice to extract from them, learning any secret they may hold. Use of this costs the caster 1d4 health that can only be healed through magical means.
