Base Class: Bard
Reflavored version of the College of the Gambler.
Soothsayer
When you join the College of Fate at 3rd level, you gain proficiency with the Insight and Deception skills and with playing/tarot cards. If you are already proficient in any of these, you may instead choose to gain expertise in them. Additionally, you can use playing or tarot cards as a spellcasting focus for your bard spells.
Twist of Fate
Also at 3rd level, you learn to use some of your natural bardic talents to manipulate fortune. When a creature that you can see within 60 feet of you makes an attack roll, an ability check, or a saving throw, you can use your reaction to expend one of your uses of Bardic Inspiration, instead treating the creature's roll as either a 5 or a 15. You can use this ability after seeing the result of the roll.
Read the Room
At 6th level, you gain advantage on any Insight (Wisdom) checks meant to assess a creature's personality, spot changes in its mood, or predict its next course of action. As long as you are not surprised, you may add your proficiency bonus to any Initiative tests.
Enigmatic
Also at 6th level, you gain advantage on any Deception (Charisma) tests meant to conceal your emotions or appear less intelligent than you are. Whenever a magical spell or effect would read your thoughts, determine the truthfulness of your statements, or compel you to tell the truth, you may make a Charisma saving throw to instead remain silent or cause the spell or effect to return no information at all.
Esoteric Reflex
At 14th level, your natural ability to assess risk works in conjunction with your arcane abilities. During your turn, or as a reaction, you may choose to end one spell you are concentrating on. If you do so, you may immediately regain one spell slot equal to the level of the spell slot used to cast the spell you were concentrating on or lower. Once you use this ability, you can't use it again until you complete a short or a long rest.
