Owen Explains It All: Tiny Terrors for Starfinder

Before we get to any OGL content, an editorial aside:

This post is tagged as an “Owen Explains It All” post because it links into a show from the BAMF podcast I’m on, titled “Owen Explains It All!“. We do episodes picking new or classic things from the zeitgeek to use as inspiration for game material, specifically the Starfinder Roleplaying Game. This article ties in to the “Owen Explains It All: Ice Pirates” episode.

In this ep. we talked about a lot of the shameless scene-stealing of Ice Pirates (and, to be honest, added content warnings we discovered we needed after watching the movie for the first time in decades — not all old content holds up), and focused on the scenes that resented a small, fast, infectious threat that serves as a B Plot in the movie.

The show has a logo and everything!

This kind of small, infectious, lurking threat is fairly common in scifi fiction, but not well-supported by most existing Starfinder monsters. It works particularly well when the PCs are stuck in a specific area, such as on a starship during a long voyage, in a city or prison complex, or taking shelter in an ancient alien ruin to escape a deadly ion storm ravaging the outside. It can also work well as a recurring threat — a tiny terror that attacks the players, works to infect one, then flees the scene only to come back again later.

So whether your PCs are dealing with an alien that burst out of someone’s chest at lunch, acid-spitting reptilian aliens working to establish dominance, or a disgusting git that’s infected your ship, you can create a new kind of threat for your players by introducing a tiny terror to your Starfinder game.


Sometimes you encounter a hostile creature that’s not a threat in a direct stand-up fight, but rather a lurking threat you have to hunt down, trap, or maybe even blow up the whole planet just to be sure. Making a tiny terror can be easy, with this template you can slap onto any thematically appropriate creature. Shrink the monster down to diminutive or tiny size (no need to change its ability scores — if PCs can tap into the cosmic forces of gravity, entropy, and magic, a 6-inch insectoid threat can carry a man away with a +8 Str bonus, if that’s what the stat block has), and add the following special rules.

Dodge And Weave (Ex): A tiny terror ignores the movement penalties for difficult terrain, and treats difficult terrain as cover against attacks made by any creature larger than it is.

Duck And Hide (Ex): A tiny terror has Stealth as a master skill. If it already had Stealth as a master skill, it gains a +1 bonus on Stealth checks. It can make Stealth checks anytime it is 30 feet or more for any observer (even if it lacks cover or concealment), and anytime it is in difficult terrain. A character that has successfully used the identify creature task on a tiny terror(using whatever is the appropriate skill for the tiny terror’s creature type), can make an Engineering check to modify any equipment that qualifies as a scanner to detect the tiny terror. Such modified scanners allow Perception check to ignore the tiny terror’s Stealth checks, though only to identify what square it is in.

Hit And Run (Ex): Once a tiny terror has successfully damaged a foe, it gains a +4 AC bonus whenever it takes the fight defensively or withdrawal actions. This ability lasts until the tiny terror makes an attack roll, or is out of combat for 10 minutes or more. As a result once a tiny terror hits (and potentially infects) a foe, it generally seeks to escape the encounter, often by fleeing to an air duct, dense foliage, or other region where pursuers cannot easily follow.

Infection (Ex): If a tiny terror’s attack doesn’t already have a disease attached to it, it gains one. if it had a curse, poison, or other affliction, this is removed in favor of a disease. A target is exposed to the disease, (which is always a physical disease — select any you like the sound of), and the save DC is typical for the ability DC of a creature of the same array and CR as the tiny terror. If the target is killed by the disease, a new tiny terror is born out of the corpse in 1d4 hours. (A tiny terror may grow into the full-sized version of the creature you apply this template to, but how long that takes is a narrative decision made by the GM based on the story’s needs.)

Terror’s Sting (Ex): A tiny terror’s attacks are highly accurate and focused enough to penetrate most defenses, but deal little actual damage. The tiny terror gains a +2 bonus to all attacks, and ignores an amount of its target’s hardness, energy resistance, and damage reduction equal to its CR. However, its attacks deal a maximum amount of damage equal to its CR (roll its damage normally, but if it exceeds the tiny terror’s CR, reduce the damage dealt to equal its CR). In most cases this means it can easily hit target’s AC and bypass defenses, but will still only do a little damage.

Anytime a tiny terror’s attack damages a target, that target is exposed to the infection (see above).
