This spell was devised by the archmage Dwarkanath to increase the variety (but not quantity) of spells normally available to a spellcaster. Essentially, Dwarkanath's arcane expander provides a number of additional spells that the wizard can select during an adventure (or group of small adventures that are encompassed in the duration). It does not, however, increase the number of spells the character may cast within a day.
For every two levels of the caster, one additional spell level's worth of spells can be memorised. In other words, should an eighteenth level wizard cast this spell, he could make selections that may be chosen from when deciding upon a spell to be cast. Be aware that the character affected by Dwarkanath's arcane expander must take the time to memorise the additional selections. Because of the nature of the spell, the recipient must begin memorising these spells within 1 turn of completing the casting of Dwarkanath's arcane expander. If multiple spells are being memorised, each must be started within one turn of the previous spell.
In order to cast this spell, the caster must gather rare oils and spices, as well as samples of brain tissue from specific spellcasting creatures (the DM should choose something appropriate for his campaign). Generally, the gold piece costs for the material components for this spell are typically 10,000 gp.
