Feat
Effortless Maintenance
The spell sustains itself while the caster looks elsewhere
A spell that requires maintenance—one spell action each round—sustains itself for rounds equal to the caster's Charisma.
During that time, maintenance costs neither a spell action nor an Action Board slot. The caster can fight, move, cast, or leave.
Only one spell receives free maintenance at a time. Starting another ends the first unless it is maintained normally. The duration resets whenever the caster maintains the spell with a normal action.
