Your ValdaSpire24Extras ValdaSpire24Extras improves in the following ways.
Avoidance
If one of your Skeleton Spirits is subjected to an effect that allows it to make a saving throw to take only half damage, it instead takes no damage if it succeeds on the save and half damage if it fails. It can't use this trait if it has the Incapacitated condition.
Improved Spectral Bolt
The damage of your Skeleton Spirits' Spectral Bolt becomes 1d6 Necrotic damage.
