* Listed below are all of the innate (non-skill) racials: *

Frontal Stun Immunity

Ogres cannot be stunned from the front, which gives them a great advantage over other races.

Enemy attacks can still push you backwards, which will interrupt your spell casting.
Tip: You can stand in a corner to avoid being pushed back.

Increased Armor Class

Iksar start with a +15 AC bonus (+17 if they are a Warrior) over other races, which scales with level. However, they cannot wear plate armor until the Velious expansion.

Increased Consumption Rate

Barbarians, Halflings, Ogres, and Trolls all consume food and drink slightly faster than other races.

Increased HP Regeneration

Both Iksar and Trolls have higher HP regeneration rates (per tick):

Level 01-19: 4 sitting, 4 rested sitting, 2 feigned, 2 standing, While Hungry: 0
Level 20-49: 4 sitting, 6 rested sitting, 2 feigned, 2 standing, While Hungry: 0
Level 50: 4 sitting, 8 rested sitting, 2 feigned, 2 standing, While Hungry: 0
Level 51-55: 8 sitting, 12 rested siting, 8 feigned, 6 standing, While Hungry: 4
Level 56-59: 12 sitting, 16 rested sitting, 12 feigned, 10 standing, While Hungry: 8
Level 60: 14 sitting, 18 rested sitting, 14 feigned, 12 standing, While Hungry: 10
Level 61-62: 16 sitting, 20 rested sitting, 16 feigned, 14 standing, While Hungry: 12
Level 63-64: 18 sitting, 22 rested sitting, 18 feigned, 16 standing, While Hungry: 14
Level 65: 20 sitting, 24 rested sitting, 20 feigned, 18 standing, While Hungry: 16

Comparatively, these are the HP regeneration rates (per tick) for all other races:

Level 01-19: 2 sitting, 2 rested sitting, 1 feigned, 1 standing, While Hungry: 0
Level 20-49: 2 sitting, 3 rested sitting, 1 feigned, 1 standing, While Hungry: 0
Level 50: 2 sitting, 4 resred sitting, 1 feigned, 1 standing, While Hungry: 0
Level 51-55: 3 sitting, 5 rested sitting, 3 feigned, 2 standing, While Hungry: 1
Level 56-59: 4 sitting, 6 rested sitting, 4 feigned, 3 standing, While Hungry: 2
Level 60: 5 sitting, 7 rested sitting, 5 feigned, 4 standing, While Hungry: 3
Level 61-62: 6 sitting, 8 rested sitting, 6 feigned, 5 standing, While Hungry: 4
Level 63-64: 7 sitting, 9 rested sitting, 7 feigned, 6 standing, While Hungry: 5
Level 65: 8 sitting, 10 rested sitting, 8 feigned, 7 standing, While Hungry: 6

Rested sitting means you've been sitting for 60 seconds or more.

A "tick" happens every 6 seconds.

It does not matter whether you are sitting or standing between seconds 1 and 5, only the 6th second.
