Been working on something that I think you will all enjoy, but here is a side idea I had while making it.
Casting Time: 1 action
Components: V,S,M(a waterclock’s hour hand)
Duration: 1 hour or until dispelled
This spell decelerates temporal effects of spells on a subject doubling the duration of all spells on the subject while watched clock is in effect. Also, the target of this spell may end it at any time to reroll a concentration check using as many dice as were rolled in the original check.
