Asksvin Hatchling
Asksvin Hatchling has 400 health.
It resists fire and poison; spirit does nothing to it at all. Blunt, slash and pierce land at full damage, so that is what to bring.
Of everything craftable, 
Frostfire Crossbow, 
Thunderblood Crossbow and 
Lightning Strike put the most damage through what it resists.
Asksvin Hatchling is the young of a tamed 
Asksvin pair. It has 400 health, half the adult total, but keeps the adult profile otherwise: resistant to fire and poison, immune to spirit damage, and already running at 9 from a walking speed of 3. Killing one returns a 20% chance each of 
Asksvin Bladder, 
Asksvin Hide and 
Asksvin Tail, so it is worth a fraction of the adult it grows into.
With devcommands enabled, this spawns Asksvin Hatchling in front of you. The third number is the level: 3 spawns a 2-star.
