Finster is as an intelligent mage. It takes him a little over an hour to finish preparations of his spells for a day. During this time he meditates, reads through spellbooks and other similar activities. He requires peace, quiet and comfort to allow for proper concentration. His surroundings need not be luxurious, but he requires they be free from overt distractions. He finds that exposure to inclement weather prevents his necessary concentration, as does any immediate injuries (although preparations go normally while he is healing from wounds from past battles). Once he was interrupted half way through his preparations and only finished half his spells.
