Boon of Jeremy - The Salamander of Fate

A blessing given to you by Jeremy - The Salamander of Fate, allowing you to witness fate to gain benefits or downsides to your next weapon attack roll, spell attack roll, saving throw, damage an enemy, or heal yourself or an ally, depending on what is witnessed. You may, as a bonus action on your turn, choose to catch a glimpse of fate. Draw a card from a standard Tarot Deck and gain the effect shown below:

• Drawing a Cups will immediately make you heal yourself or an ally within 30 ft. of you an amount equal to twice the value of the card, any value that goes over your maximum health is instead added as temporary health points.  If you draw a King, Queen, Knight, or Page of Cups this is enhanced, instead making the healing effect a 30 ft. radius sphere around you. The value healed applies to all allies and enemies within the area and yourself, with the value being based off the witnessed card, 25, 20, 15, 10 for King, Queen, Knight, and Page respectively.
• Drawing a Pentacles will effect your saving throws, you gain an additional +(half the value of the card rounded up) to your next saving throw to something you can see. If you draw a King, Queen, Knight, or Page of Pentacles this is enhanced, ensuring your next saving throw is successful unless you wish to fail instead. If you choose to succeed in this way you will immediately fail the next saving throw you are forced to make.
• Drawing a Swords will effect your weapon attack rolls, you gain an additional +(half the value of the card rounded up) to your attack roll with a weapon you are proficient with. If you draw a King, Queen, Knight, or Page of Swords this is enhanced, ensuring your next attack will hit. After this enhanced effect happens the next weapon attack made against you also has this benefit.
• Drawing a Wands will effect your spell attack rolls, you gain an additional +(half the value of the card rounded up) to your next spell attack roll. If you draw a King, Queen, Knight, or Page of Wands this is enhanced, ensuring your next spell attack will hit. After this enhanced effect happens the next spell attack made against you also has this benefit.
• Drawing a Major Arcana will make you take anywhere from 0-21 unmitigatable damage to immediately deal the same amount of damage to an enemy within 100 ft. of yourself.
