You don't so much cast a _miracle_ as request one. You state what you would like to have happen and request that your deity (or the power you pray to for spells) intercede. A _miracle_ can do any of the following things. * Duplicate any cleric spell of 8th level or lower. * Duplicate any other spell of 7th level or lower. * Undo the harmful effects of certain spells, such as [_feeblemind_](/spells/feeblemind) or [_insanity_](/spells/insanity). * Have any effect whose power level is in line with the above effects. Alternatively, a cleric can make a very powerful request. Casting such a _miracle_ costs the cleric 25,000 gp in powdered diamond because of the powerful divine energies involved. Examples of especially powerful _miracles_ of this sort could include the following: * Swinging the tide of a battle in your favor by raising fallen allies to continue fighting. * Moving you and your allies, with all your and their gear, from one plane to a specific locale through planar barriers with no chance of error. * Protecting a city from an earthquake, volcanic eruption, flood, or other major natural disaster. In any event, a request that is out of line with the deity's (or alignment's) nature is refused. A duplicated spell allows saving throws and spell resistance as normal, but the save DCs are as for a 9th-level spell. When a _miracle_ spell duplicates a spell with a material component that costs more than 100 gp, you must provide that component.
