You conjure a small wisp of magical energy that hovers in the air and follows the caster. For the duration of the spell, you gain the following effects;

• You gain a bonus +1 to you spell attacks and spell DC
• The wisp emits bright light out to 5 feet, and dim light for another 10 feet.
• As a bonus action, you can make a range spell attack against a creature that you can see within 30 feet of you. On a hit, you deal 1d4 radiant damage.

While you maintain concentration on the spell, you can dismiss or summon the wisp as a bonus action. If you dismiss the wisp, you maintain your bonus to your spell attacks and spell DC, but do not gain the other benefits until you summon the wisp.
