Creature size

A creature's size indicates how large it is, roughly communicating other parameters like the model's dimensions/how much space it physically occupies, their weight, and their ability to interact with the environment, such as via Rocky Crevices and Burrow Holes.

The weight of a creature affects what can Throw or Shove it.

• A creature may throw items and other creatures weighing up to $0.2\times {\text{Strength}}^{2}\;{\text{kg}}$ or $0.4\times {\text{Strength}}^{2}\;{\text{lbs}}$.
  • For example, with 18 Strength, one can throw objects weighing up to $0.2\times 18^{2}\;{\text{kg}}=64.8\;{\text{kg}}$ (or 130 lbs).
• When a creature's size changes, its weight will also be adjusted as necessary to conform with the above categories.

A creature's size and weight can be inspected by selecting it and choosing Examine, or targeting it with the cursor and hitting the corresponding hotkey.

Size categories

Size	Maximum weight		Example creatures
	kg	lbs
Tiny	6	12	Cats, Crag Spiders, and Air Elementals
Small	40	80	Halflings, gnomes, goblins, and sheep
Medium	200	400	Humans, dwarves, and most other playable Races
Large	5,000	10,000	Ogres, Owlbears
Huge	50,000	100,000	Ansur
Gargantuan	500,000	1,000,000	Nautiloid

Modifying size

Altered form

When a creature's form is changed (examples in table below), part of the parameters that they inherit include the form's size and weight as per the above table.

Condition	Size	Source	Duration
Disguise Self	Respective Race's (Small for gnomes and halflings, Medium for others)	Mask of the Shapeshifter ( Shapeshift)	Duration: Until Long rest
		Disguise Self
		Mask of Many Faces
		Seeming
Wild Shape	Respective creature's (ranges from Tiny for a Cat, to Large for an Owlbear)	Wild Shape	Duration: Until Long rest
Gaseous Form	Tiny	Gaseous Form	Duration: Until Long rest
		Mist Stance
		Wind Walk
Wild Magic: Cat Form	Tiny	Wild Magic: Cats and Dogs	Duration: 2 turns
Wild Magic: Dog Form	Medium
Polymorphed	Small	Wild Magic: Polymorph	Duration: 2 turns
		Polymorph	Duration: 5 turns
Toad Mode	Tiny	Dolly Dolly Dolly	Duration: 1 turn
Big Pig	Medium
Cattle Prattle	Large
Displacer Beast Form	Medium	Displacer Beast Shape	Duration: Until Long rest
Slayer Form	Medium	Slayer (Class Action)	Duration: Until Long rest

Enlarge and reduce

Furthermore, additional modifications can be made to a character's size to shift it into neighbouring categories, as per the table below.

• Creatures cannot change to categories larger than Gargantuan, or smaller than Tiny.
  • Other parameters like their physical model can still change size.
• Conditions with the same Stack ID (see below) are replaced/refreshed if another source is added; they do not stack.
  • For instance, a duergar inflicted with  Enlarged is Large, and using  Whossa Large Fellow? will first cancel Enlarged, then apply it anew.
  • Using  Enlarge  on a  Reduced character will first cancel the latter condition (regardless of initial source), then apply Enlarged, possibly changing their overall size by 2 categories.
  • Despite being a separate Condition and having additional effects,  Giant Form takes up the same "slot" as Enlarged and Reduced.
• Conditions with different Stack IDs can stack, changing the character's size as appropriate.
  • An Enlarged character that uses a Elixir of the Colossus will further increase size.
  • A creature with  Elixir of The Colossus that is then Reduced will return back to its original size, then change again as appropriate when either effect ends or is replaced.
• These changes apply after taking into account a shape/form change.
  • As such, a Medium Cat, Gargantuan Owlbear, or Tiny Sheep are all possible, amongst other combinations.

Stack ID	Condition	Size change	Source	Duration
SIZE	Reduced	-1	Oil of Diminution	Duration: 2 turns
			Sethan ( Sethan: Reduce)	Duration: 5 turns
			Reduce	Duration: 10 turns
	Enlarged	+1	Enlarge	Duration: 10 turns
			Duergars'  Enlarge
			Bigboy's Chew Toy ( Whossa Large Fellow?)
	Giant Form		Balduran's Giantslayer ( Giant Form)
ALCH_ELIXIR	Elixir of The Colossus	+1	Elixir of the Colossus	Duration: Until Long rest
