This is a feat for the Pathfinder roleplaying game, inspired by the Ritual Casting feat from D&D 4e. It is licensed under the Creative Commons Attribution 4.0 International license and uses Open Gaming Content from the Pathfinder Reference Document. A D&D 3e / 3.5e conversion is also available.
You are trained in the use of rituals, which are versions of common spells that can be cast at-will, provided you have enough time and expensive reagents.
Prerequisites: 1 skill rank in Knowledge (arcana), Knowledge (nature), Knowledge (religion), Heal, or Perform (any).
Benefit: You obtain a basic ritual book (which has the same weight and game statistics as a common spellbook), which has two 1st-level rituals scribed in it.
You know how to inscribe new rituals into your ritual book, and how to cast rituals from it.
Scribing new rituals
A ritual may be inscribed into a ritual book from any spellbook or scroll, provided it does not deal Hit Point damage. To do so, use the same rules and skill check DCs for adding Wizard spells to your spellbook, but substitute one of your ritual casting skills for the Spellcraft checks as follows:
|Spell List||Required Skill|
|Sorcerer / Wizard||Knowledge (arcana)|
Spells which cure Hit Point damage are an exception. Use a Heal skill check for them instead.
Spells from spell lists other than those listed above cannot be cast as rituals.
At any time, you may roll a skill check as appropriate for the ritual (see "Scribing new rituals," above) to cast a ritual from either your ritual book or a scroll containing a spell which could be inscribed into one. If cast from a scroll, the act of ritual casting erases the text, just as casting a spell from it does.
The DC for casting a ritual is equal to 20 + caster level if cast from a scroll, or 15 + caster level if cast from your ritual book. (You may choose what caster level to use if you are casting it from your ritual book, up to a maximum of the number of ranks you have in the required skill.) To cast rituals from a scroll or from someone else's ritual book, roll a skill check as appropriate for the ritual to decipher it first, as with Wizard spells.
If you are casting the ritual version of a spell which would normally require expensive material or focus components, you must have those components on hand when casting it from a ritual book.
Casting a spell as a ritual takes considerably longer than casting spells normally does:
|1 standard action||1 minute|
|1 full round||10 minutes|
|1 minute||1 hour|
|10 minutes||1 hour|
|1 hour||1 hour|
Spells with other casting times, such as a free or immediate action, cannot be cast as rituals.
If you fail the skill check required to cast a ritual, you do not cast that ritual, and any consumable items required to cast it (including the scroll if you are casting from one) are lost.
To cast a ritual, you must have the required reagents on hand. These cost as much as the material components required to scribe a scroll of that spell, and take on a form appropriate to the skill required to cast the ritual:
|Required skill||Reagent Type|
|Heal||Either rare herbs or incense|
|Knowledge (arcana)||Arcane dust|
|Knowledge (nature)||Rare herbs|
|Perform (any)||Arcane dust|
You may also use residuum, which is a form of distilled magical essence obtained by disenchanting a magic item. To disenchant an item, a character with the appropriate item creation feat and a caster level equal to the item's must spend as long as it would take to create that item (maximum 8 hours). The amount of residuum obtained by disenchanting a magic item is equal in value to the gold piece cost required to create that item. Artifacts cannot be disenchanted.
Reagents other than residuum can be purchased at temples, magic item shops, specialty shops catering to adventurers, and from druids or rangers who are open to dealing with outsiders. A character may also roll Spellcraft or Survival to gather reagents, with one check representing one day's work and providing an amount equal to the gold piece value that would be added to an item with that Craft check result. The DM / GM may rule that you cannot roll this check if you don't have access to an appropriate node of magic or source of raw materials.
Increase the number of skill ranks required to take the feat from 1 to 4, and reduce the maximum caster level when casting rituals from a ritual book from "equal to your number of skill ranks" to "equal to your number of skill ranks -3."
