Benjamin Ripley

Scanner. Benjamin Ripley can learn everything there is to know about whatever/whoever he is currently fighting. Up to 2 pieces of information at a distance of up to 30ft, and up to 5 pieces of information when in melee range. Once Benjamin Ripley has learned a target's vulnerabilities, he chooses one of them and declares it out loud; he gains advantage on all combat rolls that exploit the declared vulnerability.

Relentless. Upon passing a Constitution Saving Throw (DC 10), Benjamin Ripley can choose not to be knocked unconscious if his HP drops to 0, instead raising his HP to 1. This effect can be used up to three times a day, if Benjamin Ripley hasn't defeated any enemies, and up to five times a day if he has defeated at least one enemy.

Unending Rage. After utilizing the Relentless trait once, Benjamin Ripley will enter into a state of unbridled rage, and must always attack the target nearest to him. Unending Rage auto-cancels when Amon-Gorloth's Elder Child is activated, as well as when Benjamin Ripley defeats an enemy within a turn of activating Unending Rage.

Amon-Gorloth's Elder Child. At the cost of all of his hit-points, Benjamin Ripley can enter a state of pure balance, giving him temporary access to the 20th level spell Star-Stomper for a single turn.

Multiattack. Benjamin Ripley makes two Mjölnir attacks, and can throw Mjölnir, which he can recall to his hand with a bonus action.

Mjölnir. Melee Weapon Attack: +15 to hit, reach 5 ft., one target. Hit: 4d8 + 10 lightning  damage.

Throw Mjölnir.  Ranged Weapon Attack: +10 to hit, reach 100 ft., one target. Hit: 4d8 + 10 lightning damage

Recall. Bonus Action. Benjamin Ripley calls out to Mjölnir, which goes through anything in its way and returns, on its own, to its master's hand.

Star-Stomper. 20th Level Spell: +20 to hit, reach ∞ ft., all available targets. Hit: 20d20 + 50 radiant damage. All targets hit must pass a Constitution Saving Throw (DC 20), on a failed save,  the target is knocked unconscious instantly, on a passing save, the target receives half of their current hit-points in damage (after regular damage calculations) and is frightened.

Frightful Presence. Each creature of Benjamin Ripley's choice within 120 feet of it and aware of it must succeed on a DC 17 Wisdom saving throw or become frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, with disadvantage if Benjamin Ripley is within line of sight, ending the effect on itself on a success. If a creature's saving throw is successful or the effect ends for it, the creature is immune to the Benjamin Ripley's Frightful Presence for the next 24 hours.

Legendary Resistance (3/Day). If Benjamin Ripley fails a saving throw, it can choose to succeed instead.

Magic Resistance. Benjamin Ripley has advantage on saving throws against spells and other magical effects.

The Jacket. Any time Benjamin Ripley is targeted by a magic missile spell, a line spell, or a spell that requires a ranged attack roll, roll a d6. On a 1 to 5, Benjamin Ripley is unaffected. On a 6, Benjamin Ripley is unaffected, and the effect is reflected back at the caster as though it originated from Benjamin Ripley, turning the caster into the target.

Attack. Benjamin Ripley makes one melee or ranged Mjölnir attack.

Move. Benjamin Ripley moves up to half his speed.
