Focus of Extension
Rarity: Legendary
Aura: Generic
This item takes the form of any class-specific spellcasting focus.
When a spell is cast with this focus present (not necessarily used as a component), once per day, the caster can choose to extend the duration of the spell whose duration is not "Instantaneous" to one full day. If such a spell was already being extended, that effect concludes. If the spell is concentration, the caster need no longer concentrate on it (as if the focus does the concentration). If the spell has contingencies about ending due to certain distances or differences in location from the caster, the focus may be treated as the caster for such calculations, in addition to the real caster, with the calculation chosen that gives the best chance for the spell to continue.
If the same spell cast at the same level on the same targets (and with the same specifics and details) is cast and extended using this focus for each of 7 consecutive days, the duration extension for the final cast becomes "Until dispelled", as long as the same focus isn't used to extend another spell or destroyed.
Effects that cause the spell to end normally may still dispel it. For example, if the spell says the caster may end it as an action, this can be done by the caster at anytime. (If it doesn't, any caster with access to the focus can use it to cast another spell, and, in doing so, effect the ending of the former spell.) Similarly, the spell ends if no valid target exists for it anymore--but especially powerful combinations of indefinite spells can overcome this (see below).
A typical usage is to leave an environmental effect in place for as long as needed; for example, Alarm, Minor Illusion, Silent Image, and so forth. More devious users may use enchantments instead, such as Friends or Suggestion, comforted by the extended, or even indefinite, time. Perhaps the most dangerous spells are transmutation and necromancy, such as Regenerate and (True) Resurrection; the latter has effects not unlike the Necromancer's Ring (see), but it might be impossible for the target to dispel it even if they want to. Similarly, a great fiend might make permanent a cast of Dominate Person/Monster and guard their focus on their person, in a great vault, or even throw it into the open ocean, gaining--if their spell save DC is high enough relative to the target's Wisdom--a permanent slave. A permanent Wall of Force may be as powerful as Imprisonment, but the target still suffers the effects of age, lack of food/water, and, eventually, suffocation, unless those are accounted for otherwise. Not all effects are bad; indefinite Mage Armor and indefinite Longstrider can permanently increase some important statistics. All of these are examples, and the lasting effects are up to interpretation by the DM.
Such foci can be created by targeting a focus with a 9th level cast of Permanency, an extremely rare and difficult-to-find spell, likely to only be a single-use scroll. [The spell is attested in 3.5e, but not in 5e; a wizard that can cast Wish should be able to emulate the effect.]
The focus retains its usual AC and HP. When destroyed, the spell it is extending, if any, ends.
Per Detect Magic, the focus has an aura of no particular school affiliation.
