Maintain

Some spells can be "maintained", meaning they can continue to function (without being re-cast) as long as the original caster puts the mana/fatigue cost into it. By default, you cannot "hand off" a spell to someone else,Basic Set: Characters, p.238 although Lend Spell can allow this! Furthermore, Ceremonial Magic can allow supplemental energy from others.
