Since we can customise skills, why not let us customise our own scorpions?
Break the scorpion traps into the following aspects:
Durabilty (HP)
Intelligence ( % chance of following owner and not getting lost)
Damage
Poison Damage
Fire Resistance
Water Resistance
Earth Resistance
Air Resistance
Another approach will be to add in a 'Mechanic' skill which allows varying customisation to traps. Then the player will draft a template which describes the scorpions and go to the blacksmith and get it done.
