Floating disc is a handy spell to magically carry items around for you. They let you keep more stuff to sell or use without worrying about burden. It’s not advisable to put truly precious items on them, but they’re perfect for the loot you gain in day to day adventuring. They are particularly useful to magical characters, who traditionally have low strength and up to three sets of gear to carry around.

If discs have major drawbacks it’s that they don’t follow instantly, so they don’t work at all with ‘shoprun’ commands. They also dump everything on the ground if you forget to recast the spell to maintain them. Legends speak of a ‘disc trick’ ability that would let thieves get all the items on someone’s disc, but otherwise it’s impossible for anyone but the owner to access them.

Looking at a disc will show how far it’s hovering off the ground. This has no meaning except to tell you the remaining minutes left in the spell before it collapses. One inch equals one minute remaining duration.

This spell creates a disc that floats in the air behind you.
You can put things in it so that it carries them for you.
Maximum duration for this spell is LVL/2 minutes,
but in any case it will last at least 2 minutes.
You can also update the floating time by casting the spell
at certain disc. Floating discs are known to be unstable.
You can refer a floating disc with "<owner>'s disc", or
"my disc", which works for the owner.
If mud crashes, you lose the items on the disc.  POOF.
Note:  You can 'dissipate' or 'dispel' your floating disc
if you wish to end the spell prematurely.

Brightens the room you’re in and lasts about 1 minute per player level. Since light interferes with spawnform, shadows, and other things, infravision is usually a better way to maintain your ability to see. If you are an ent or otherwise need regular light, illumium shards are a better method.

While most activities which require the light of day can be planned to
coincide with these hours, there are times that this is just not possible. One
of the easiest forms of magic, is to use it to create a source of light. 
Magic itself usually glows, due to its unstable power when it is beheld on
this plane of existance. Therefore bringing a controlled steady magical light
is a trivial task for users of magic. The more powerful the caster, the longer
the light will last. To dismiss the light, just touch it.

In most respects this spell mimics the ‘wings’ attribute that some races have. Most importantly you can fly over water and lava, but a few areas will also let you float up to things or over obstacles. Since things like falling and height are borderline random in how they’re enforced, your mileage will vary. This spell is usually better than water walking.

This spell dates back to the origin of practiced magic. One of the earliest
tests of magical power, was the ability to magically lift and support objects
without any assistance except from the magic itself. By keeping only a minor
amount of concentration, a caster can make himself float off of the ground.
This helps him avoid any perils that might come from having contact with the
ground, such as floating over water.

Rift pulse is the core offensive spell for riftwalkers. It is a cold damage spell that will never disrupt control of your entity. The damage of this spell is tied to the power of all of your entities.

The pulses of a high end riftwalker aren’t half bad in terms of damage over time, assuming the enemy in question is vulnerable to cold. The only major drawback of this spell is that it doesn’t give or benefit from mage reputation.

A skilled riftwalker can pull a small amount of energy from the rift world,
transform it into an incredibly cold substance, and hurl it towards an
opponent. As the power of the riftwalkers entities grows, the amount of energy
the riftwalker can extract from the rift world will increase.
