You create three glowing darts of magical force. Each dart hits a creature of your choice that you can see within range. A dart deals 1d4 + 1 force damage to its target. The darts all strike simultaneously, and you can direct them to hit one creature or several.
At Higher Levels.
When you cast this spell using a spell slot of 2nd level or higher, the spell creates one more dart for each slot level above 1st
An invisible barrier of magical force appears and protects you. Until the start of your next turn, you have a +5 bonus to AC, including against the triggering attack, and you take no damage from magic missile.
You emit a freezing blast of ice around you, capable of rooting your foes in place. Each creature on the ground within 15 feet of you must succeed on a Constitution saving throw or be restrained by the ice until the end of your next turn. A creature restrained by the ice can use its action to make a Strength check against your spell save DC. On a success, it frees itself.
You set an alarm against unwanted intrusion. Choose a door, a window, or an area within range that is no larger than a 20-foot cube. Until the spell ends, an alarm alerts you whenever a Tiny or larger creature touches or enters the warded area. When you cast the spell, you can designate creatures that won't set off the alarm. You also choose whether the alarm is mental or audible.
A mental alarm alerts you with a ping in your mind if you are within 1 mile of the warded area. This ping awakens you if you are sleeping.
An audible alarm produces the sound of a hand bell for 10 seconds within 60 feet.
