Arena:The Known Spellbook
These are all of the spells available for purchase from Mages in the Mages Guild. Though these standard spells can be useful, you can also create your own spells. The original manual divides the spells into circinates of increasing level based on spell cost. Those are in fact merely notional; you can be any level and purchase and cast any spell if you have the requisite spell points.
In the tables below, the cost column represents the cost to buy the spell. You can buy any spell regardless of whether you have enough spell points to cast it. The casting cost in spell points of the spell is cost divided by two divided by your level. For example, if you are tenth level, to cast Pitfalls costs 600 / 2 / 10 = 30 spell points.

* Some spells that the manual mentions as being part of the Known Spellbook are not for sale in any Mages Guild. Those include Cure Disease (cost: 375), Cause Disease (975), Purify (2590), and God's Fire (3750). However, you can still create these spells using the Spellmaker service.
** Sanctuary does not quite work as advertised. While monsters will not actively come after you or look in your direction, the spell-casting ones will still throw their spells your way (while otherwise seeming to ignore you).
*** "Permanent" is actually temporary. As long as you are on the dungeon level of the object you destroyed or created, what you did is permanent. However, when you leave the level, the entire level returns to its original state.
- A round equals one minute of in-game time.
- Walls and floors save vs. magic when you try to destroy them. This seems to imply that walls and floors may require multiple attempts to destroy. In fact, if you can destroy the object at all, you will do so on the first try. The ones you can't destroy have 100% protection from magic, and so always make the save. The rest have 0% protection and so never save.
- While the spells in The Known Spellbook are more or less useful, you are best advised to create your own spells. You can create spells that make much more efficient use of your time (and your spell points/restore power potions).
