You can attack twice instead of once whenever you take the Attack action on your turn.

Cecil can dash as a bonus action, or combine movement with disengage and leap farther than normal.

You have mastery of unarmed combat and monk weapons. You can make an unarmed strike as a bonus action, use Dexterity instead of Strength for attack and damage rolls with monk weapons and unarmed strikes, and use your Dexterity modifier for Grapple and Shove save DCs when using an unarmed strike.

When an attack hits you and deals bludgeoning, piercing, or slashing damage, you can use your reaction to reduce the damage by 1d10 + your Dexterity modifier + your monk level. If you reduce the damage to 0, you can spend 1 Focus Point to redirect the force to another creature in range, forcing a Dexterity save.

You can use a reaction to reduce falling damage by five times your monk level.

If Cecil hits with Flurry of Blows, he can choose to add effects such as pushing, tripping, or preventing opportunity attacks, depending on his subclass if any is chosen later.

Cecil can dodge while disengaging, helping him weave through danger with monkish agility.

While you are not wearing armor or wielding a shield, your AC equals 10 + your Dexterity modifier + your Wisdom modifier. This is not used here because your tortle natural armor is better.

You gain Focus Points equal to your monk level. You know Flurry of Blows, Patient Defense, and Step of the Wind, which let you spend Focus Points to strike more, defend yourself, or dash and reposition. Your Focus Point save DC is 8 + your proficiency bonus + your Wisdom modifier.

Your speed increases by 10 feet while you are not wearing armor or wielding a shield.

When you roll initiative, you can regain all expended Focus Points, and if you do, you regain hit points equal to your monk level plus your Martial Arts die roll. Once you use this feature, you must finish a long rest before using it again.

Choose a monk subclass. This character has not yet selected a subclass, so this feature is not otherwise expanded here.

Once per turn when you hit with a monk weapon or unarmed strike, you can spend 1 Focus Point to force a Constitution save. On a failure, the target is stunned until the start of your next turn. On a success, its speed is halved until then and the next attack roll against it has advantage.

You know where and how to find the hidden or forgotten lore of the multiverse. Libraries, archives, monasteries, and old records are never far from your thoughts, and scholars, scribes, and keepers of knowledge are inclined to help you when they can.
