Weight of 1000 Years (5e Spell)
From D&D Wiki
|Casting time:||1 action|
You close your eyes and focus on the Vortex of Time, condensing the memories of the past millennia into a single thought, then gesture above a creature within range and snap your hand down as all these thoughts and memories are solidified and forced upon the target, hitting them with agonizing mental damage.
That creature must make a strength saving throw. On a failed save, it takes 1d6 Psychic damage and is knocked prone. On a successful save, it takes half as much damage and doesn't fall prone.
At higher Levels: When you cast this using a spell slot of 2nd level or higher, the damage increases by 1d6 for each slot level above 1st.
