Manna is the name of the food miraculously produced for the Israelites in the desert in the book of Exodus. Manna ceased to appear when the Israelites first harvested their crops in their new homeland. In Hebrew, manna "what is it". By extension "manna" has also been used to refer to any divine or spiritual nourishment. According to Judeo-Christian tradition, the mysterious substance which was provided miraculously by God to the Hebrews during their forty years in the desert descended by night like hoarfrost in the form of coriander seed of the color of bdellium It was collected before sunrise, before it melted in the sun. The people ground it, or pounded it, and then baked it A double portion was to be found on the day before the sabbath, when none was to be found. When the Hebrews arrived at Gilgal, and began to eat the grain grown there, the manna ceased. Some people belive that manna tasted like whatever the person eating it wanted it to taste like. This way although they ate the same thing daily for a long time, they were always finding enjoyment in eating it. Hope this Helps, Tiff

Since this question is in the Magic category, I am going to avoid the biblical definition of manna and stick to the category: In standard D&D, (Dungeons and Dragons) magic is represented as spell slots which the character fills with spells. Wizards are the most limited - they must fill those slots before adventuring, and if a wizard has chosen not to learn 'knock' on that day, or has cast his only memorisation of it, he is incapable of using it. Sorcerers are less limited - they can select which spell they will use, as and when they require it, but from a much smaller pool of possible spells. For instance, even the most powerful sorcerer can only ever know nine of the most basic (0-level) spells, while the least of wizards knows every one of them. However, both magic-using classes can use broadly similar amounts of magic in a day, whatever the method of selection. A manna-based system allocates a pool of points to a character. The character then uses those points to cast spells, and the size of this pool acts as the limitation on the amount of magic which can be cast. Under a manna based system, each spell has a manna cost, and the character spends manna points to power those spells. Thus, a spellcaster with 20 manna points may be able to use that power to cast two fifth level spells. Alternatively, it may be sufficient to power ten first level spells, numerous cantrips, or a single ninth level spell. It is the next step along the road which led from wizard to sorcerer, into a character where not only are spells selected as required, but also spell slots. As to the other question, regarding a wizard's wheel, the following answer has been posted on Answerbag by another member (Hungry Guy) and explains the wizard's wheel better than I can: A Wizard's Wheel (sometimes called a Warlock's Wheel) is a small disk. It can be made out of any material, such as wood, metal, glass, plastic, etc. Its purpose is rather insidious. The wizard sets it in motion, causing it to spin ever faster and faster. This will, in time, consume all of the manna in the immediate vicinity of the wheel. You do not want to be anywhere in the vicinity when this occurs. When all of the manna is consumed, the mundane laws of physics will take over. The wheel will be spinning at an ungodly RPM: one million, one billion, or even one trillion RPM, or more. Thus, in one tiny little disk, the energy equivalent of a sizeable atomic bomb will be contained in the form of rotational inertia, and suddenly released. Further, the wizard, who may be aged well beyond the life expectancy of a typical mortal, would instantly die and turn to dust the instant all the manna is consumed.

Oh, come on guys! ...er, and gals. Manna is like some sort of ambient magical energy, often considered finite. I'm not sure of the original theory, but authors I've read have had conflicting ideas on its source, what its good for, who can use it, and whether or not it can all be used up or if its self-renewing.

I thought is was a breadlike food in Biblical days.

If you're talking about manna in video game terms it means the amount of power and energy you process to a given point and after it runs out, it must be built up again.

Manna is actually a Indian term accociated with the Hindus.It is also referred to the milk from the heavenly mother.The intoxicating substance is a metaphor for spiritulal enlightenment.When one drinks of the heavenly manna they gain knowlege of all things.One gains a form of spiritual immortality.I have studied this subject for years.

mana is spiritual energy, as most spells in games such as diablo and warcraft, the spells cost mana, when you run low on mana you no longer have the energy to perform your spells until you have regenerated your mana
