Looking good! I especially love the Scar!
Yes, the features are meant to be a bit abstract, so as to not limit your creativity. A couple of minor suggestions...
Maybe update the "Can attack three times per turn." It's a bit redundant, as the MA score dictates that they have 3 attacks already... perhaps because it is a plant, a couple of special feature options could be:
- Regenerates 1DM per turn? OR
- Toxic poison on it's surface, and anybody who touches it has to make 1SV Tuff
On the CA, maybe it can be updated to be more in line with the "Conditional Save" mechanic, which requires a successful save before they can make further actions? So maybe something like "CSV Will for toxic spray"
Keep up the good work, and feel free to enter more cool monsters!
