Some spells require the caster to actively maintain the spell's effects. At the end of a maintenance spell's duration, the caster pays 1 Strain to maintain the spell for an additional duration count. Each spell the caster is currently maintaining increases the Casting Threshold of additional spells by 1.

The caster can drop maintenance at any time, and the spell will disperse at the end of its current duration count.

The following situations require the caster to make a roll against RES to hold a maintenance spell in their mind -

• Taking Damage
• Suffering a Mental Condition

If a caster falls unconscious, any spells they are maintaining are dropped.
