SRD - Recharge Magic

At its heart, the recharge magic variant is simple: A well-rested spellcaster can cast any spell he knows or has prepared, but then either rolls a die to find out how many rounds must pass before spells of that level become available again (if it's a general recharge spell) or loses access to that spell for a specified time (if it's a specific recharge spell). Spell slots are never expended; they just become temporarily unavailable.

Recharging doesn't require any actions and doesn't provoke attacks of opportunity. As long as a spellcaster is alive, he naturally recharges his energy.

With this variant, all spellcasters effectively become spontaneous casters like sorcerers, choosing a spell each round from a list. For sorcerers and bards, the list is fixed (just as it is for sorcerers and bards who aren't using the variant), but other spellcasters set their available menu of spells when they prepare spells for the day. With the recharge variant, there's no reason to prepare the same spell in more than one slot. Because sorcerers and bards don't have the flexibility of choosing a new menu of spells each day, their general recharge times are shorter.

Some classes, such as the cleric and the druid, have limited spontaneous spellcasting ability. Such a character can convert any spell on his daily list into the appropriate spell (such as either cure wounds or inflict wounds for a cleric, or summon nature's ally for a druid), but doing so replaces the converted spell on the cleric's daily list with the spell cast in its place. This happens only once per spell level, because after that point the relevant cure or inflict spell appears on the spell list as if it had been prepared.

This variant distinguishes two kinds of spells: spells with general recharge time (usually no more than a few rounds) and spells with specific recharge times (which range from minutes to hours).

Recharge Times for Other Spells

Combat-oriented and short-duration spells (those lasting up to 1 round per level) typically have a general recharge time. Conversely, spells with longer durations have specific recharge times (the longer the duration, the longer the recharge time). Any spell with an expensive material component or an XP component has a general recharge time.

Enchantments usually have a specific recharge time ranging from 30 minutes to 12 hours. This limitation prevents characters from simply charming everyone in the tavern in the space of a few minutes.

Divinations typically have a specific recharge time, often in the neighborhood of 6 hours, to prevent their abuse in the hands of curious characters.

Powerful illusions and permanent "trap"-type spells have specific recharge times of 12 hours to 1 day, unless They're expensive to cast.

GENERAL RECHARGE SPELLS

Table: General Recharge Times tells how many rounds must pass after the casting of a general recharge spell before another spell of that level becomes available.

For example, Boredflak is a 4th-level wizard. His 2nd-level spells (the highest possible level he can cast) and 1st-level spells (the second highest possible level he can cast) take 1d6+1 rounds to recharge, and his 0-level spells (the third highest possible level he can cast) take 1d4+1 rounds to recharge. When he attains 5th level, his 3rd-level and 2nd-level spells take 1d6+1 rounds to recharge and his 1st- and 0-level spells take 1d4+1 rounds to recharge. (Specific recharge spells have their own recharge times that don't match these values.)

Another example: Aliester the 10th-level sorcerer casts fireball in the first round of a fight. Once he casts the spell, he rolls 1d4 to determine his recharge time. He rolls a 2, so he must wait 2 rounds before he regains access to 3rd-level spells. In the following round, he casts cloudkill, one of his highest-level spells. Rolling a 4 on 1d4, Aliester is dismayed to learn he must wait 5 (1d4+1) rounds before he can cast cloudkill again. In the next round, he casts magic missile, rolling 1d3 afterward and getting a result of 1 for a 1-round recharge time. In the following round, Aliester regains access to his 3rd-level spells, so he can cast another fireball if he likes, or he can cast magic missile again (because the 1-round recharge time for his 1st-level spells has elapsed).

Countering and Dispelling

For example, if a 5th-level cleric casts deeper darkness to dispel a daylight spell, he can cast another 3rd-level spell (including deeper darkness) 1d6+1 rounds later. If he instead casts deeper darkness to darken a passageway, he can't use deeper darkness again for 24 hours, but his other 3rd-level spells are available to be cast.

BEHIND THE CURTAIN: RECHARGE MAGIC

This is a high-powered variant, because spellcasters can cast their staple combat and healing spells all day long. This means that the PCs face almost every encounter fully healed, and rarely do spellcasters have their spell lists significantly depleted. Spellcasters may have some specific-recharge utility and protective spells that they won't be able to cast before every fight, but they always have access to their highest-level combat and healing spells. And it's those spells that largely comprise a spellcaster's contribution toward overcoming a given encounter.

As with most high-powered variants, recharge magic works only if every spellcaster in the campaign is using it, including powerful NPC spellcasters. A recharge-variant lich, for example, is a terror for high-level PCs to behold.

As the GM, you have to plan for a party of PCs that can adventure all day long, beginning every fight in a more or less fully rested state. This prospect can be thrilling for players, who no longer have to face the disappointment of a retreat to town just when They're on the cusp of the adventure's climax. But when PCs don't need to retreat to heal and prepare new spells, the GM ends up running more encounters per game session, which means a measure of extra preparation.

As a rule of thumb, a group of four PCs that includes two recharge variant spellcasters can handle encounters of an Encounter Level equal to the characters' average level +2. The fights will be exciting ones; every room in the dungeon becomes as perilous as a typical adventure's climax. But the PCs face each one with full resources, so the denizens of the dungeon can't defeat them through depletion and attrition. If your group likes knock-down, drag-out, set-piece battles, the recharge magic variant lets you fight more of them.

Characters attain new levels faster in terms of both player time at the gaming table and character time in the game world. You can regard this as an additional benefit, or you can reduce experience point awards across the board to compensate.

The recharge magic variant makes spellcasters stronger overall, and it makes nonspellcasters stronger if you assume They're getting fully healed after every encounter. But in some respects it makes them weaker as well. Even the most powerful wizard can't cast two fireball spells in consecutive rounds with this variant. The teleport spell has a specific recharge time of 4 hours, so a character can't teleport someplace, cast a spell, then teleport away again (unless he uses word of recall or greater teleport for one of the legs of the journey). Strategies that rely on repeated use of the same spell aren't viable if the spell in question has a specific recharge time. Depending on the strategy, its chance of success might improve or worsen if a character is relying on a general recharge spell. In short, the recharge variant gives casters a lot more power in exchange for slightly less flexibility with regard to general recharge spells and significantly less flexibility with regard to specific recharge spells.

There's an obvious way for characters to compensate for the diminished flexibility: scrolls. In general, scrolls become more useful in the recharge variant game world, so they may be more prevalent. Conversely, wands are somewhat less useful, because every spellcaster can crank out his staple spells dozens of times. When a character can cast lightning bolt fifty times in the space of an hour, that fully charged wand of lightning bolt is much less impressive. If you use the recharge magic variant, consider reducing the percentages of minor and medium wands on Table: Wands by 5% and increasing the percentages of minor and medium scrolls by the same amount.

One less obvious change posed by this variant is that lower-level spells retain more importance for high-level spellcasters. With the general recharge rules, even the most potent spellcaster can't use her best spells more than two or three times in a major fight. Spells two, three, or four levels below the maximum get cast while the spellcaster waits for the heavy artillery to get reloaded.

As the GM, you have to contend with other subtle changes wrought by this variant. Monsters with spell-like abilities usable at will are diminished somewhat, because true spellcasters can cast spells so frequently. Monsters with spell-like abilities aren't actually weaker—and their Challenge Ratings needn't go down as a result—but they feel less special and more like spellcasters with a static spell list.
