Spellcasters in REFUGE purchase “spell slots” in which they memorize specific spells each LP. Each spell slot can hold up to a certain level of spell; a caster can memorize lower level spells into a higher-level slot if they choose to do so. Higher level spells are generally more powerful and more difficult to learn than lower level spells.
Higher level spell slots must be built upon knowledge of lower level spell slots. To represent this, spell slots must be purchased in a pyramid shape, where there must always be more slots on a lower level before you can purchase a higher-level slot. Once you have reached at least four slots in a specific level, you can purchase an equal number of the next higher-level slots. In addition, a spell slot pyramid may never be too “empty” of higher-level spells. Similarly, you can’t have more than one “gap” of two spells between two levels—for example, you couldn’t have four 1st level spells, two 2nd level spells, and zero 3rd level spells.
When a character chooses which spells to put in which slots at the start of an LP, they may only use spells for which they have a spell book. Within this book are recorded the specific spells you can memorize. Multiple people can memorize from the same spell book, but there are specific abilities and rituals for which you may always want your own spell book available.
Slots are purchased as if you were building a Pyramid. The lower level spells build the base for higher learning. As an example, let’s start with a newly built Celestial Scholar
As you can see, this build uses a Pyramid shape.
Now that the Pyramid is being built it must follow a certain pattern. You always require more slots on a lower level before you can purchase additional slots on the next higher level. We will continue to build the Pyramid (assuming the player is going to continue to build with a goal of reaching 9th level slots as quickly as possible).
Step 2: As you progress, your next purchase would be a 2nd level slot, then a 3rd, then a 4th. Things to remember: When you get to a 4th slot purchased on a specific level, you no longer need *more* slots on a lower level, but only an *equal number*. If you do wish to purchase a 5th slot of 1st level, you can always do so (which would allow you to purchase a 5th second level spell slot and so forth).
Step 3: Now we can add a 5th Level Slot. To purchase a 6th level slot, you need to purchase a 3rd, 4th, and 5th level slot first.
Note that the pattern is very set as to which Spell Slots must be purchased unless you wish to buy more than four Spell Slots of any one level. There is potentially no limit as to the number of Spell Slots per level that can be purchased if this pattern is maintained.
You can have a pyramid with nine 1st level Spell Slots, eight 2nd level Spell Slots, seven 3rd level Spell Slots, and so on up to one 9th level Spell Slot.
To the right is what your final Pyramid might look like. Once you have completed that, you can finish building your column of 4-9th level spells.
