Celestial Blessing

Call upon the powers of your Celestial Patron for a blessing in your time of need. While you are in combat, you can choose one willing creature you can see, that creature gains resistance to one damage type of your choice and 1d4 temporary hit points. This spell ends after 1 minute, or the target no longer has temporary hitpoints granted by the spell. If the creature is not willing, it must succeed on a wisdom saving throw.

If cast on yourself, add your charisma modifier to the temporary hit point roll. Additionally, until the end of your next turn, your next Celestial Blast (or Eldritch Blast) will restore 1d4 healing light dice at the end of your turn, if it hits. These dice cannot be use on the same turn they are gained.

If cast on a creature already under the effects of Celestial Blessing, this spell instead refreshes the duration of the spell on the target, you may change the resistance granted by the spell and grant a new set of temporary hit points (A creature can have at most one type of resistance from this spell).

The number of dice used for temporary hitpoints increases with level: 2d4 at fifth, 3d4 at 11th and 4d4 at 17th

This spell must be cast as your first action, your turn ends immediately upon casting this spell. You do not make any more actions, bonus actions or move after casting this spell.
