Feral Magic

Feral Magic is a supplement for the Mausritter TTRPG that can be adapted into other tabletop games with ease, especially any old-school style game like Into the Odd, Cairn, or Knave. It can be used in any setting or adventure, and alongside any other module. The downloads include a tri-fold pamphlet available in A4 & US Letter sizes.

When mice use spell tablets, they tap into a vast well of arcane power that is woven deep into the fabric of the natural world. This magic can be wild and unpredictable, even feral. Calling on this mysterious power can occasionally unleash feral blasts of untamed magic that can have varied, uncontrollable, and frequently entertaining results.

Whenever someone casts a spell, they roll d20 to see if they trigger a blast of feral magic. If they roll a 20, they must roll on the Feral Magic Blast table to see what the effect is. Each time they do not trigger a blast, the trigger expands by 1 (meaning the next roll will trigger a feral blast on a 19-20, the next time a blast is not triggered it will expand to 18-20, and so on).

The blast trigger expands each time a blast is avoided and is reset to 20 when a blast is triggered, as well as at the end of each day. The blast trigger is shared across all players. Feral magic blast effects take place immediately.

The table includes 50 different effects that can be triggered, for example:

• If you die within the next minute, you immediately come back to life.
• You can't speak for the next minute. Whenever you try, sand falls out of your mouth.
• Cast Darkness with 3 [DICE] centred on yourself.
• Your tail permanently doubles in length.
• You turn into a spider for 1 minute, with your stats changing accordingly.
• All hirelings in your party take the Frightened condition with you as the source of their fear.
• You are covered in stone armour for 1 minute, giving +2 to your armour.
• A frog controlled by the GM appears in a space within 1 foot of you, then disappears 1 minute later.
• A swarm of d20+10 butterflies surrounds you for 1 minute before flying off.
• You and all nearby allies have incredibly itchy feet for 24 hours.

...and 40 more!

Some effects are positive, some are negative, and some are purely narrative. Have fun with this! When a feral blast happens, make the effect entertaining and memorable. All the spells used in the effects come from the core Mausritter rule book.
