At your touch, wet blood on a surface shifts and reforms into a pattern of crimson blotches. This blood print is unique to the particular creature to whom the blood belongs, but you can determine the creature's kind (such as human, gnoll, deer, or fire giant) by examining the general shape. A print can be preserved by pressing a sheet of paper against it. If this spell is cast twice, it is possible to match samples of blood originating from the same creature by comparing the prints.
Up to three creatures of your choice that you can see within range must make Charisma saving throws. Whenever a target that fails this saving throw makes an attack roll or a saving throw before the spell ends, the target must roll a d4 and subtract the number rolled from the attack roll or saving throw.
At Higher Levels: When you cast this spell using a spell slot of 2nd level or higher, you can target one additional creature for each slot level above 1st.
You spread cracks in the magical energy that suffuses the multiverse. For the duration, whenever a spell is cast within range, roll a d6. On a 1, the spell casting fails, expending a spell slot as normal, but not consuming expensive material components.
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.
