Greater Refresh Magic (3.5e Spell)

Noticing that your spell is about to expire, you infuse it with magical energy to keep it going for another minute or two.

You can use greater refresh magic to prolong ongoing spells that have been cast on a creature or object, to temporarily bolster the magical abilities of a magic item, to prolong ongoing spells (or at least their effects) within an area, or to prevent another spellcaster from countering or dispelling a spell. Greater refresh magic can prolong spell-like effects just as it does spells.

Note: A spell with a duration of instantaneous or permanent can't be prolonged (in the former case, the spell's over almost as soon as it begins, and in the latter, the spell lasts forever anyways), and greater refresh magic cannot prolong a concentration-dependent continuous magical effect if its caster ceases to concentrate on it.

You can choose to use greater refresh magic in one of three ways: a targeted refresh, an area refresh, or an anti-dispel:

Targeted Refresh: One object, creature, or spell is the target of the greater refresh magic spell. You make a refresh roll (1d8 + ½ your caster level, maximum +10 at level 20) for the spell or for each ongoing spell currently in effect on the object or creature. You add the result of the refresh roll to the number of units (rounds, minutes, hours, days, weeks, years, etc., as listed in the spell description) remaining in the spell's duration. If a spell can be ended early by a part of its own effect (such as being discharged, a target succeeding on a saving throw, being dismissed, its caster losing concentration on it, etc.), greater refresh magic only extends the spell's maximum duration; it does not prevent the spell from ending early if its conditions are met. A spell whose effects are modified throughout its duration (such as storm of vengeance or creeping cold ) continues to change following the same pattern (for instance, storm of vengeance would revert back to its 1st-round effects on round 5, while creeping cold ' s damage output per round would continue increasing by 1d6 on each successive round). A spell designed to last for a static amount of time, not affected by caster level in a formulaic fashion (such as flensing, which is designed to last for 4 rounds) cannot be made to have a remaining duration longer than its given maximum duration plus half that duration (flensing, for instance, can have no more than 6 rounds remaining at any given time through greater refresh magic).

If you target an object or creature that is the effect of an ongoing spell (such as a monster summoned by monster summoning), you make a refresh roll to prolong the spell that conjured the object or creature.

If the object that you target is a magic item, you make a refresh roll to bolster the item's magic - temporarily if the item's magic is permanent, or permanently if it can be depleted (such as a wand). Items that are explicitly single-use, such as potions and scrolls, do not get extra uses; instead, add half of your refresh roll to the item's caster level (this effect lasts until the item is expended, but gets erased if the item's properties are suppressed or erased by dispel magic, mage's disjunction, or a similar spell). For items with charges (2 or more uses), you add your refresh roll to the remaining number of charges if the maximum is 50 (this ignores any rules stating that an item can't be recharged, but not any rules that make something terrible happen if the item is overcharged!) If the maximum number of charges is not 50, divide 50 by the item's maximum number of charges, then divide your refresh roll by the result, rounding down to the nearest whole number (minimum 0). (This decreases the amount of charges that can be restored to an item with a low maximum.) An item that can be used a limited number of times in a given interval gains a number of uses equal to half your refresh roll. Regardless of whether or not the item regains charges/uses on its own, greater refresh magic cannot cause it to have more charges/uses remaining than its normal maximum (if greater refresh magic would give it more charges/uses than its maximum, its number of remaining charges/uses is set to the maximum). For items that have or grant a bonus, that bonus is increased by half your refresh roll for 2d4 rounds.

Recharging magic items can be dangerous! An item that has charges or a limited number of uses per interval can only be guaranteed to be recharged if its spell level is 5th or lower. If the spell level of the item is 6th or higher, there is a cumulative 20% chance per spell level above 5th that the item being recharged will explode, utterly destroying it (it can't even be restored by wish or miracle) and dealing 1d6 points of backlash damage to you per spell level of the item plus 1d6 backlash damage per charge it contained (including the charges granted to it by greater refresh magic), plus that same amount of damage as raw magical energy to anything within a 5-foot radius of the exploding item (which may very well include you!) A Reflex save is allowed for half damage from the explosion for any creature caught in the explosion (the one that had the exploding item on its person at the time takes a -8 penalty), and all creatures caught in the explosion are allowed to apply spell resistance. Intelligent items are entitled to a Fortitude save to resist exploding, and an artifact that would explode simply fails to be recharged instead. (The exception to this rule is a staff of the magi, which explodes as if it had been used to perform a retributive strike, either obliterating whomever was holding it or sending him/her to another plane without a Reflex save. This also happens if this spell causes a staff of power to explode.)

Area Refresh: When greater refresh magic is used in this way, the spell affects everything within a 20-foot radius.

For each creature within the area that is the subject of one or more spells, you randomly choose one of those spells with any method that the DM deems appropriate (picking cards, d% roll, etc.) and make a refresh roll to prolong that spell. (The DM may choose to stack the chances in any way he sees fit, but either granting each spell an equal chance to be affected or giving better odds to spells with a higher caster level or lower spell level is recommended.)

For each object within the area that is the target of one or more spells, you make refresh rolls as with creatures. Magic items are not affected by an area refresh.

For each ongoing area or effect spell whose point of origin is within the area of the greater refresh magic spell, you can make a refresh roll to prolong the spell.

Ongoing spells whose area merely overlaps that of the greater refresh magic spell are unaffected.

If an object or creature that is the effect of an ongoing spell (such as a monster summoned by monster summoning) is in the area, you can make a refresh roll to prolong that spell in addition to refreshing a spell targeting it.

Anti-Dispel: Greater refresh magic can be used to counter any spell being used to terminate a magical effect, as long as that spell is 5th-level or lower (4th-level or lower for bards, as greater refresh magic is a 5th-level spell for bards). When used in this way, greater refresh magic targets a spellcaster and is cast as a counterspell. Greater refresh magic is always capable of countering greater dispel magic or any weaker variant (but not necessarily a more powerful variant); likewise, greater dispel magic and its more powerful variants can counter refresh magic without needing to roll a dispel check. (Weaker versions, such as dispel magic, must roll a dispel check as normal.)

To counter a spell of greater than 5th level other than greater dispel magic (or a spell of greater than 4th level if cast by a bard), a dispel check is necessary, just as if you were casting greater dispel magic. (Just like greater dispel magic, the dispel check is 1d20 + your caster level, maximum + 20, against a DC of 11 + the other spell's caster level.)

Greater refresh magic can be used to defeat any counterspell.
