Boon of the Spell Lord TTR

Your saving throw spells that deal damage have their DC increased by 3. Your spells of 7th level and lower deal full damage when a creature saves against them by a margin of 5 or less (including if upcast). 1st through 8th level spells that have a saving throw deal additional damage dice equal to your spellcasting modifier  (including if upcast. Spells that include a saving throw component only get the additional damage if you use the component that forces the creature to make a saving throw) Your primary spellcasting ability score and its maximum increase by 2. All creatures automatically assume you're the most powerful spell caster in the room.  This boon can only be chosen once.
