Alacrity

The use of an alacrity spell allows the wizard to speed up the casting of spells of 5th level and lower. Only spells that are cast within the alacrity spell's duration are affected.
Casting times of 2-5 are reduced by 1: casting times of 6-9 are reduced by 2; and a casting time of one round is reduced to a casting time of 8. Casting times for spells which require more than 1 round are reduced by 20% (e.g., an animate dead spell affected by alacrity could be cast in only 4 rounds). Spells which have a casting time of 1 are not affected by this spell.
The material component is destroyed when the spell is cast.
