Arcane Amplification

You tap into the weave of magic and amplify its power within a 20-foot radius around you. For the duration of the spell, all spells cast within this area have their potency increased by 1 level, up to a maximum of 9th level. For example, a 2nd-level spell cast within the area becomes a 3rd-level spell, while a 9th-level spell cast within the area remains at 9th level. Additionally, any saving throws required by spells cast within the area have disadvantage.

However, the increased potency of magic comes with a cost. Whenever a spell is cast within the area, the caster must make a DC 15 Constitution saving throw or suffer a level of exhaustion. If the spell being cast is of 6th level or higher, the DC increases to 20.
