Starfinder – Unleash the Zillo Beast

Sometimes you miss a week and the fire hose of Starfinder news goes off. So, since last post we’ve got the new Starfinder 2e playtest which includes a couple of encounters to use those ancestries and classes we’ve been getting. It’s fun stuff with some basic hints about how the Corpse Fleet will look in the new addition, as well as the Azlanti Star Empire. In fact, there’s a bit of a spoiler in that second encounter, as it would seem there is a war on with the Azlanti. Expect more news on that front in the future. The encounters are also a preview of what monsters will look like in the new system, and I don’t think it’s a spoiler to reveal there are a LOT more Starfinder 2E monsters in the pipeline.

Starfinder 2E Playtest Feb 2024

Happy Mechsgiving! In other Starfinder news, the last 1E adventure path has been released with the gloriously named Mechageddon! Taking place on the kaiju plagued world of Diamalko, the AP follows a group of cadets just starting their careers in the ‘valko’ mechs of Diamalko’s reclaimation force, beginning an epic battle to retake the planet from the kaiju colossi that have all but laid waste to their world. If you are a fan of Robotech, Evangelion, Pacific Rim, or any number of other mech and kaiju stories, this is the AP you have been waiting for. I can’t wait to give it a play myself!

Finally, in non-Starfinder but somewhat adjacent news, the Bad Batch Star Wars cartoon came to a close, seemingly wrapping up the loose threads of the Clone Wars series and putting that period to bed (for the moment at least). It’s not a surprise to long time blog fans that I’m a die hard Star Wars nerd, especially the animated series, so I’m a bit sad to have the show end, even though I feel like it was a great conclusion that did justice to the characters. Also, as long as we are talking about the Bad Batch and kaiju, a certain beast played a pivotal moment in the last episode. The Zillo Beast, one of Star Wars’ own kaiju, had their moment in the sun. Of course, such a fearsome creature would make a great Starfinder monster…

Once again I’ll be using the expanded size table here and updated Kaiju template here. Particularly when balancing encounters against player driven mechs, that Kaiju template helps level the playing field. So let’s get to it…

Hurl Debris (Ex) The mighty strength of a zillo beast allows it to turn nearly anything into a ranged weapon. A zillo beast is assumed to have such debris available (either loose or readily torn from the environment without requiring an extra action) unless the GM rules otherwise. Hurled debris has a range increment equal to the zillo beast’s Strength modifier × 5 feet. Such attacks also create difficult terrain in a 10-foot-radius area around the target.

Absorb Electricity (Ex) a zillo beast is not only not harmed by electricity, it actively absorbs and feeds on the energy. The beast automatically fails saving throws against weapons and magical effects that deal electricity damage. However, such an effect merely heals it for 1 Hit Point per 3 damage the effect would have dealt. Once it has taken 60 or more damage from an electrical source the beast increases its size by one category as a free action (from Gargantuan to Colossal, from Colossal to Vast, etc). As well as increasing in size, it also gains a +2 circumstance bonus to Strength checks, a +4 circumstance bonus to damage, and +10 ft. of reach. It can increase in size this way up to 3 times (reaching Immeasurable) but the effect fades one size category per hour, unless the zillo beast has an available source of electricity to feed on continuously. The beast will actively seek out generators and large batteries to feed on if possible, and depending on the capacity of the source it finds, it can heal and grow using that source as well, at a rate determined by the GM.

As always, if you like this or any of the other content here on Solo Run Studio I would welcome a little of your support through Ko-fi. Until next time Starfinders!
