Has anyone worked up the numbers on these guys? I'd love to throw them at my group.

All I can say is

They tried that in Rebels. It didn't work so well...

Thanks for that. I was trying to forget those things existed. The Arachnophobia is strong with this one...

They look just like the Knobby White Spiders of Dagobah which eventually grow into Gnarl Trees. The biggest difference between them and the Krykna is the number of legs.

They are actually based upon the concept art for the Knobby White Spiders, which is neat.
