Arcane Overdrive Elixir

A crackling, prismatic fluid that hums with unstable arcane power.

You may drink this potion as a bonus action. You enter an arcane overdrive for 1 minute. While active, you gain the following effects:
• Your spell save DC and spell attack rolls gain a +2 bonus 
• Once per turn when you deal damage with a spell, you deal an extra 1d10 force damage
• when you cast a spell of 1st–5th level, you may treat it as if cast using a spell slot one level higher (max 5th level) a single time within the span of the potions effects.
• You have advantage on Constitution saving throws you make to maintain concentration 

When the effect ends, you:
• Take 6d10 necrotic damage that ignores resistance and immunity 
• Gain 2 levels of exhaustion 
• Must succeed on a DC 15 Constitution saving throw or drop to 0 hit points and begin making death saving throws
 
Once you drink this potion, you can’t benefit from another Arcane Overdrive Elixir for 7 days.
