Hero System Kobold
Very good!
I'll be using these babies in my own Fantasy Hero Ccampaign.
Only one real complaint. If you have read "Tucker's Kobolds" (or the AD&D Monster Manual for that fact), then you know that Kobolds have average human intelligence. That would put them at 10 instead of 8.
The tail, not being a extra limb, is a good suggestion also.
By the way, I ran a party of 5th, 6th and 7th level characters up against twenty Kobolds once. The Kobolds were straight out of the book with random treasure. The PC's lost. Over half of them were killed. Thank you Tucker!! You proved that weak stats don't mean near instant death.
