In DDO, the size of a creature has several implications in combat:
- Armor class: Smaller creatures are harder to hit than larger creatures. This is most notably visible in the Halfling Size Bonus - halflings (as well as gnomes) gain +1 to their AC (1 per size category).
- Attack bonus: Smaller creatures can apply more precision to their movements and gain bonus to attack rolls. Larger creatures receive a size penalty (1 per size category).
- Larger creatures enjoy the benefit of extended reach.
Carrying capacity: small creatures have 3/4 of the maximum carrying capacity (compared to medium-sized creatures)
- Smaller creatures can hide more easily than larger ones (4 bonus/penalty per size category).
- Small creatures are also less intimidating than larger ones (4 bonus/penalty per size category).
Contrary to PnP, in DDO small races (halflings) do not use different (smaller) equipment with reduced weapon damage dice.
