Homebrew (Tome of Heroes)
When you join the College of the Cat at 3rd level, you gain proficiency with the Acrobatics and Stealth skills and with thieves’ tools if you don’t already have them. In addition, if you’re proficient with a simple or martial melee weapon, you can use it as a spellcasting focus for your bard spells.
Also at 3rd level, you learn to stalk unsuspecting foes engaged in combat with your allies. When an ally you can see uses one of your Bardic Inspiration dice on a weapon attack roll against a creature, you can use your reaction to move up to half your speed and make one melee weapon attack against that creature. You gain a bonus on your attack roll equal to the result of the spent Bardic Inspiration die.
When you reach 6th level in this class, you gain a climbing speed equal to your walking speed, and when you use Inspired Pounce, you can move up to your speed as part of the reaction.
Beginning at 6th level, you can attack twice, instead of once, whenever you take the Attack action on your turn. In addition, when you use two-weapon fighting to make an attack as a bonus action, you can give a Bardic Inspiration die to a friendly creature within 60 feet of you as part of that same bonus action.
Starting at 14th level, while a creature has one of your Bardic Inspiration dice, it has advantage on Dexterity (Stealth) checks. When you have no uses of Bardic Inspiration left, you have advantage on Dexterity (Stealth) checks.
