Alas

Incorporeal Movement. Alas can move through other creatures and objects as if they were difficult terrain. He takes 5 (1d10) force damage if he ends his turn inside an object.

Avoidance. If Alas is subjected to an effect that allows him to make a saving throw to only take half damage, Alas instead takes no damage if he succeeds on the saving throw, and only half damage if he fails.

Arcane Ward. Alas is protected by a magical arcane ward with a hit point maximum of 9. Whenever Alas would take damage the ward takes it instead. If this damage reduces the ward to 0 hit points, Alas takes any remaining damage. Whenever Alas casts an abjuration spell of first level or higher the ward regains hit points equal to twice the spell's level. The ward regains all of its hit points after Alas completes a long rest.
