Spellduelist

You have studied the art of spell dueling, perhaps under the famed evoker Gabal in the small school he maintains in Gate Pass, or at the Lyceum in Seaquen. Thanks to extensive practice with dueling other spellcasters, you gain the following benefits:

• Increase your spellcasting ability by 1, to a maximum of 20
• You know how to convince an onlooker that you're casting a spell when you actually are not. You can pretend to cast a spell as bonus action. The spell must be one you can prepare, and any onlooker who would use a reaction to you casting a spell - such as by attempting to use counterspell or performing a readied action - must make a Wisdom (Insight) check contested by your Charisma (Deception) check to realize the deception, or their reaction is used upon a failure as if you had actually cast the spell. Opportunity attacks and readied actions are taken, and the reaction for counterspell is used but the spell slot is not, as there is not a valid target. You advantage on Charisma (Deception) checks. You cannot casr any other spell on this turn other than the spell you were pretending to cast or a cantrip with a casting of 1 action. If you actually cast a spell this turn, anyone who wants to use a reaction must have decided to contest your deception and have succeeded.
• You have advantage on Wisdom (Insight) checks to determine if another spellduelist is pretending to cast a spell and Intelligence (Arcana) checks to identify a spell being cast.
