Looped Projectile (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Components:||V, S, M (a thrown weapon or projectile etched with silver runes worth 25 gp and a silver stopwatch etched with runes worth 250 gp)|
|Duration:||Concentration, up to 1 minute|
As part of the action used to cast this spell, you must make a ranged weapon attack with the thrown weapon or projectile material component of this spell at one creature within the spell's range. If the projectile hits, it deals its normal damage plus an additional 1d4 force damage.
Starting on your next turn, as long as you are maintaining concentration on the spell, you can use your action to click the stopwatch. This reverts the projectile back to a slightly different starting state, undoing any damage it did previously and allowing you to attack with it again, this time by making a ranged spell attack roll. At the beginning of every turn you spend concentrating on this spell, the projectile gains an additional 1d4 force damage.
The first ranged spell attack roll you make with this spell is made with advantage, as the reverted projectile surprises the enemy. The DM may rule other scenarios in the usage of this spell which may give you advantage
If you hold concentration on the spell for the spell's entire duration, you lose control of the projectile as it flies towards the target one final time. Make a ranged spell attack against the target. Hit or miss, the projectile explodes violently and is destroyed.
At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the projectile gains an additional 1d4 force damage per higher-level spell slot every turn.
