Spell Cannons


Spell Cannons

Pages: 35

Game System: d20/OGL, Pathfinder

Genre: Sci fi, Fantasy, Steam punk

A spell cannon is a clockwork, steam powered, blunderbuss-like device that uses ammunition known as spell crystals to shoot spells. Cannons come in several sizes ranging from as small as a handgun to as big as an artillery piece. While the giant spell cannons are the most impressive with their astounding range and firepower, it is the smaller, handheld weapons that see the most use. 

No longer are lightning bolts, fireballs, rays, gasses, clouds, and webs the exclusive arsenal of wizards and sorcerers. With modern advances in technology, anyone can buy an equalizer and shoot these powerful spells like a master wizard. Of course, truly powerful cannons are going to be expensive. But even a small, cheap spell cannon is better than not having one at all.

 This supplement covers everything you need to add this new technology to your fantasy, sci-fi, or steam punk campaign, including:

 An Overview of Spell Cannons -

  • Their Size -light, one handed, two handed, Huge, Gargantuan, and Colossal
  • Their range, cost, effectiveness, and firepower


Spell Crystals -

  • The ammunition for spell cannons
  • Sample spell crystals with range, damage, cost and other stats included.


Crafting -

  • How to create a cannon, a crystal, and attachments.


New Spells -

  • Shadow bolt
  • Incinerate
  • Ghoul arrow
  • Plus 10 More


Spell Cannon Attachments and Accessories-

  • Targeting sequencers
  • Autoloaders
  • Polarized Reciprocators
  • Recompensating Conflagators
  • Plus many other mechanical devices to improve the power and performance of your spell cannon, no matter how big or small.


This file also features an introduction to the new Telestic Engine Campaign Setting, a post-apocalyptic science fiction realm of steam powered space travel where spell cannons have existed for hundreds of years. This section includes an overview of the setting, the history, and a brief sample quest, Horrors of the Ice Moon.

 This file is fully illustrated, thoroughly hyperlinked, and packed with cosmic ideas of an anachronistic vision of a futuristic past where ferocious aliens armed with mechanized, chainsaw-like swords battle with psychic warriors and knights clad in steam powered body armor.

Poisonous Plants

Available Now!

This beautifully illustrated PDF features 5th edition D20 rules for 67 deadly plants from our own world including hemlock, nightshade, and hellebore.

Each plant is presented with a stat-block outlining its habitat, size, frequency, medical uses, damage, saving throws, and challenge rating. Most entries feature additional rules for creating herbal, alchemical, and magical substances. 

With this supplement you can:

  • Craft insecticide from white cedar.

  • Brew healing balm from nightshade.

  • Extract weapon poison from bush rope.

  • Empower your necromancy with baneberry.

  • Fight oozes with myoporum.

  • Enhance your protection spells with oleander.

  • Use jimsonweed to target objects with fly spells.

  • Use bay laurel to enhance your augury spells.

  • Brew a sleep potion from black locust.

  • Create dozens of other herbal and alchemical concoctions!

Heavily researched, the effects of these poisons mirror reality. Some cause paralysis, blindness, or terrifying hallucinations. Some cause psychic damage. A few contain acid. A couple cause creatures to take radiant damage from the sun.

Some plants are only toxic under certain conditions. Others are only toxic to certain creatures. Many can be mistaken for something else. A few are consumed deliberately. Those that affect herd animals can precipitate a famine. When famine strikes, characters are even more likely to eat toxic plants.

All types of poisons exist in the plant kingdom; ingested, inhaled, injury, and touch. Most weapon poisons are easily extracted.

Druids and characters proficient with alchemy kits, herbalism kits, or cook's utensils will find this information extremely useful. All other characters will find these rules make the wilderness much more dangerous.

To help DMs use these plants, each is presented with a challenge rating. There are also suggestions for challenging high level characters with these plants. 

Beware the fireweed that grows in damp soil!

Shun the sweet redoul!

Avoid the sandbox tree and its exploding fruit!

Fear the orcs with monkshood on their blades!

Never touch the gimp-gimpy!

Enhance the verisimilitude of your games with this collection of poisons, herbal remedies, foods, alchemical substances, magical creations, and DM inspiration.

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.
