A player's **burden** is a measure of how much difficulty they are having carrying things and moving around due to the encumbrance of their inventory.

## Burden calculation

Your burden is calculated as follows:

- Add up the weight of all items in your possession, in all your containers.
- Worn items count as half their weight.
- Items held in one hand count as twice their weight.
- Items held in two hands count as 1.5x their weight.

- Determine your maximum carrying capacity as:

Maximum carrying capacity (lb) = 1.89 * (20 + strength + strength^{2}/5)

This gives:

- 8 strength: 77.112 lb
- 9 strength: 85.428 lb
- 10 strength: 94.5 lb
- 11 strength: 104.328 lb
- 12 strength: 114.912 lb
- 13 strength: 126.252 lb
- 14 strength: 138.348 lb
- 15 strength: 151.2 lb
- 16 strength: 164.808 lb
- 17 strength: 179.172 lb
- 18 strength: 194.292 lb
- 19 strength: 210.168 lb
- 20 strength: 226.8 lb
- 21 strength: 244.188 lb
- 22 strength: 262.332 lb
- 23 strength: 281.232 lb
- 24 strength: 300.888 lb
- 25 strength: 321.3 lb

- Divide the first by the second to get your burden level.

## Effects of burden

Burden has the following effects:

### Dexterity penalties

- 50-74% burden results in a -1 dex penalty.
- 74-99% burden results in a -2 dex penalty.
- 100% burden results in a -3 dex penalty.

### Picking up and dropping things

- You cannot pick things up if they would cause you to go over 100% burden.
- If your burden changes such that it exceeds 100% (for example, due to a loss of strength), then you will automatically drop items to reduce it below 100% again.

### Combat efficiency

- Burden negatively affects one's 'to-hit' chance with all weapons.
- If fighting unarmed, then there is an additional 'to-hit' penalty from burden.
- Burden negatively affects one's ability to successfully parry or dodge an incoming attack.
- An additional penalty to dodging occurs if your burden is over twice your dexterity stat.
- Burden increases the action point cost of dodging.

### Buoyancy

The more burden a player has, the more trouble they will have staying afloat while swimming. This can be counteracted somewhat by effects that increase a player's buoyancy, such as being a witch or wearing an aquamarine magick crystal or swim ring.
