Your Constitution score is increased by 3, and your maximum Constitution score is increased by 4.

Trolls are physically mature by the age of 15, and may be functionally immortal.

Note for Players

The longer a troll lives for, the more prone to mutation it becomes. Mutations can range from tumorous growths and fungal blooms to a second head with its own functioning brain. If you are playing a troll above the age of 100 years old you should discuss with your DM what kind of mutations you might have and what (if any) gameplay impact they produce.

Trolls are selfish and though they are not prone to acts of wilful cruelty, they feel no remorse at consuming sentient beings, often alive and sometimes whole. Your alignment tends towards chaotic evil.

Trolls are tall and ungainly, yet surprisingly powerful, with an adult reaching between 8 and 12 feet tall, and averaging 800 to 1,600 lbs. Your size is Large.

Your base walking speed is 30 feet.

You can speak Giant, and can read and write it with effort.

You are also fluent in "Trollspeak", a guttural mix of common, goblin and orc – though you are not proficient in any of these three languages, you can attempt to communicate simple concepts to creatures that do speak those languages, and may be be able to comprehend a few words in return, at your DM's discretion.

You can see in dim light within 60 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

You have advantage on Perception checks that rely on smell.

Your claws and teeth are natural weapons with which you may make unarmed strikes, inflicting d6 slashing damage (claws) or d6 piercing damage (teeth) instead of the normal bludgeoning damage.

Additionally, if you made an unarmed strike with your claws as part of an Attack action during your turn, you may use your bonus action to make an additional unarmed strike with your off hand claws (if they are free) or your teeth.

At the start of each of your turns you may spend up to one quarter of your maximum hit die (rounded up) to recover hit points as you would during a short rest. You may only do this if you did not take any acid or fire damage since your last turn (or the start of combat). You may do this while incapacitated or unconscious.

Additionally, when taking a short rest, if you have no hit dice remaining, you will immediately gain one. Also, should you lose a limb, it will fully regrow over a number of hours equal to 1d6 + your total number of missing/regrowing limbs.

Note for Dungeon Masters

Due to their Regeneration a troll player is not easily killed – if reduced to 0 HP they can spend hit dice to recover at the start of their turn, unless they took acid or fire damage since their last turn (or the start of combat). Enemies aware of this should try to prevent it, attacking a troll player with acid or fire, and seeking to inflict failed death saves to prevent their return.

You have disadvantage on Persuasion checks with smaller creatures that do not know Trollspeak (comprehension through spells is insufficient), and who are not already friendly towards you or your kind.

You may find that most strangers from smaller races will be openly fearful, or even hostile towards you, and will actively seek to flee or to drive you out of town unless convinced otherwise. Even those who allow you into their towns may be reluctant to share information, or to provide accommodation or any other assistance.

Note for Dungeon Masters

This trait should be used to counterbalance the strength of a character – a heavily optimised troll should find social situations more tense and likely to get out of hand and overuse of Intimidation should have consequences, while a less optimised character may find townspeople, though wary, will be easier to convince through gestures of kindness or good deeds.

The following are the key differences when playing as a Large creature compared to a Medium one:

• Your carrying capacity is doubled.
• You occupy and control a 10 foot square during combat.
• You cannot be Grappled, Shoved etc. by Small or Tiny creatures.
• You can squeeze through a gap (or doorway) large enough for a Medium creature to move through normally. You cannot fit through Small or Tiny sized gaps or doorways.
• To ride a mount it must be Huge or larger, or be mechanically or magically able to carry you.
• You require four times as much food and water as a Medium creature. You will require four rations (1 day) for a single day, food for five Medium creatures will feed you plus one other Medium creature and so-on.
• Full cover for a Medium creature may only provide you with 3/4 Cover, 3/4 cover for a Medium creature may only grant half cover, and half cover for a Medium creature may provide you with none.

Note for Dungeon Masters

You should consider a player's size when handling many other aspects of the game – enemies might get a Perception bonus to spot a Large player that is sneaking without taking extra precautions, or a bonus to Insight to see through the disguise of a still clearly Large creature, and in combat a Large player may be a more obvious threat for an enemy to aim for than a Halfling Rogue.

As a Large creature you can wield weapons as follows:

• You can wield weapons crafted for a Large creature without penalty.
• You have a -5 penalty to attack rolls for light weapons created for a Medium or smaller creature.
• You may wield one medium sized two-handed or versatile weapon in one of your hands with the same effectiveness as if you were wielding it in two. You may only wield a ranged weapon in this way if it has the loading or reload property.

Large weapons can be found on Large monsters, or crafted specially, both at your DM's discretion.

Large Weapon Crafting Suggestion

• Increase the weapon damage by +2, or add reach.
• Double the base cost and weight of the weapon and any ammunition it requires.
• A Large weapon wielded by a Medium creature loses the light property if it has it, gains two-handed, and has -5 on attack rolls if heavy. Large weapons cannot be wielded at all by smaller creatures.

To add a Large weapon on D&D Beyond, add the medium sized weapon as normal then customise – set cost and weight to double the normal values, add the damage bonus (or add Reach to notes), add Large to notes, optionally rename it.
