Berdrum's Chronometer

You touch one object and create a small, hourglass-shaped mark on the object. You then verbally designate a set amount of time such as 10 seconds, 4 hours, 3 minutes and 24 seconds, etc as well as a sound to play. Numbers are then projected on top of the mark, counting the hours, minutes, and seconds within the designated time. Upon reaching said time, the mark will disappear and the designated sound goes off, being heard from up to 10 feet away.

Alternatively, you can touch a willing creature, putting the mark somewhere on their body. You set the time as normal except instead of numbers projecting off of the mark, the creature will be able to keep track of the timer mentally, always being aware of how much time is left and when the timer goes off. Additionally, no sound is played when the timer goes off.

A maximum of 5 timers may be set at once. If an additional timer is created beyond the maximum, a timer of your choice previously made is cancelled. Additionally, a timer can be cancelled by touching the mark once again to have it disappear.
