Core 8 Spell Casting


"A stream of butterflies pours from the mouth of a mage stumbling over the words for a spell of light in an unsuccessful attempt to illuminate the shadowy dungeon. A divine caster opens a demonic rift after losing control of the chaotic energy of a curse removed from a fellow adventurer. Lightning snaps viciously around the conjurer, shocking everyone in the vicinity - the components listed on the scroll of charming must have been..falsified"

Welcome to the Core 8 Spell Casting system! A much grittier and exciting twist on the original spell casting system of OSE. I set out to make a system that…

1. Increased the potential for dangerous and unpredictable magic while maintaining a level of common and reliable.

2. Gave players more creativity and flexibility with how they use magic.

3. Felt less gamey and more thematic (“consuming your core” instead of “using a memorized spell”).

A well-rested mage with a clear mind can easily remember the words and motions used to cast the spell. But as the mage tires through the continual twisting of reality, the likelihood of deadly side effects increases. Instead of being limited by game numbers, the player is restricted by the increasing potential of doing something extremely dangerous. Magic may be common, but any with a bit of sense would know not to be greedy and tamper beyond what they are capable of handling.

Please let me know what you think, feedback is welcome!

Note 1: I have included two PDF's in the download. One is in a booklet format and the other is standard. To print the booklet, make sure your printer is set to Double Sided (short edge).

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
