The Book of Dorim the Bulkhead Brawler

[Nukatha]

One minor note: Dorim is height 4 without climb. Axegrinders and Migol are height 3 and have climb x2. So, his climbing ability matches the D&D dwarves. After his move buff, on a bonding turn, Axegrinders can climb a 4-height cliff while Dorim can only scale 3 at a time.
Just something to keep in mind, as I think each other Small unit (Repulsors excepted) has climb or flying.
