Comments from the Finger: The perfect counterpart to the Chronomancer, a wizard who can control time and likely comes from the future, is the Caveman: unintelligent, unskilled, and very, very strong. (I can only hope a few more of these decent barbarian types makes up for the difficulties we've had with them previously).
The most primitive of the savages, the prehistoric warrior hails from the remote regions of the world, or the far reaches of time, where dinosaurs still roam the world. Your fury is truly primal, and your methods crude, but you may stand tall atop the primordial food chain among the strongest creature ever to have lived.
Beginning when you select this path at 3rd level, you possess the antediluvian might necessary to pierce any foe's defenses. While raging, your melee attacks ignore resistance to bludgeoning, piercing, and slashing damage.
At 6th level, you have advantage on Animal Handling checks and Persuasion checks with creatures that have no language or share no language with you.
At 10th level, you have advantage on Constitution checks against exhaustion and do not suffer levels of exhaustion from a forced march.
Massive Weapon Fighting
By 14th level, you are experienced at hunting colossal creatures with weapons of the same scale.
You can construct a massive weapon with 1 week of work requiring twice the normal weapon's price in gold, or you can commission one from a blacksmith for a comparable price. You have proficiency in a massive weapon if you have proficiency in its normal counterpart.
Massive weapons deal twice the number of damage dice as their normal counterparts. When you score a critical hit using a massive weapon against a creature, it must make a Constitution saving throw (DC = 8 + your Strength modifier + your proficiency bonus) or be stunned until the beginning of your next turn. While you are raging, you may attack with massive weapons normally. Otherwise, you may only attack with a massive weapon once each turn.
