The Expand spell increases the capacity of the enchanted container.  It is a part of [[https://forum.wurmonline.com/index.php?/topic/146986-sindusk-server-mods/|Sindusk's server side Spellcraft mod]].

===== Crate Rack =====

==== Important Note ====

Special care must be taken when using an expanded crate rack in a vehicle.  If you unload crates from an expanded crate rack in a vehicle directly to the ground the crates will become "ghosted".  The crates will show on the ground but they are actually still in the crate rack you "unloaded" them from.

A crate rack in a vehicle that has had crates moved out of it will show that it has crates, but if you expand the crate list the crate list will show empty.  A sign that your crate rack has ghosted crates in it is if the crate rack appears empty but is higher than 6.5kg in weight.

There are two ways to fix this issue:

1. Move the crates back into the crate rack, then move them from the crate rack to the vehicle inventory first, then unload the crates from the vehicle inventory.  If the crates were moved to various containers and you can't remember where you will have to resort to number 2 below.

2. Put in a /support ticket to have the crate rack destroyed by a GM.  If there are any crates they will drop out of the crate rack unless the already popped (no longer exist to the server).  Loss of crates due to this is common.

You can move crates between crate racks in vehicles without issue.  It is only when you unload crates out of an expanded crate rack in a vehicle directly to the ground that it happens.

The best practices when using crate racks in vehicles:

* Always move from crate rack to crate rack only.  Do not unload from an expanded crate rack in a vehicle to the ground.  Or...

* Keep the crates in the expanded crate rack and instead offload the items out of the crates into other containers.  If you never move crates out of an expanded crate rack in a vehicle you don't have to worry about the ghosting issue.

An unexpanded crate rack can hold 30 large crates or 51 small crates.  An expanded crate rack can hold up to 100 large crates as per below.  I haven't tested small crates yet; I will update this sentence when I do.

===== Notes =====

Author's note concerning expand effect modifier (the server-side config setting that determines the expand effect):

* expandEffectModifier: Determines how much larger the containers become.
* Spell power directly determines the increase. 
* A 10 cast will make the container 10 times larger any other number: quadratic progression up to effectModifier additional volume.
* An effectModifier of 10 will give 2.5 times additional volume for a 50 cast and 10 times additional volume for a 100 cast.

Manytox (player) on calculating expand:

* Expand multiplies volume by a factor of 1 + ((Expand ^ 2 )* 0.0004).
* Each size axis value gets multiplied by the cube root of that, then gets rounded down to the lower integer.
* For liquid containers, size won't change, but volume will be multiplied too.
* Size values also have a ceiling with expand, 1200, which actually reduces the size value for a couple of items. But for most usages that won't matter.
* Keep in mind cast powers have decimals, and the value you see is rounded down.
* You can have two containers that display the same expand cast, but when you get to testing their volumes (or even sizes!) empirically they will be slightly different.
* Runes for size and volume get applied before expand, but the order does matter because in both occasions the values get rounded down, since it is converting a float into an int.
* Lastly, for rough calculations, 50 expand is x2 volume, 100 expand is x5 vol, and 113 expand is my favorite number, 6.1076.
