Had a sampling kit equipped for this:
You slam into the rodent and deal 16 melee damage before it can fend off the attack.
The rodent lunges forward and bites you for 2 melee damage. The site of the wound burns.The rodent slips closer and bites you, dealing 1 melee damage.
You snap at the rodent like a muzzled beast, ramming your headgear into it for 19 melee damage.
The rodent lunges forward and bites you for 2 melee damage. The site of the wound burns.You've won the battle!
You found: 3 pairs of large spider legs
After the combat, you patch yourself up, healing 6 hit points.
You've earned 2 XP in Strength
Gained 2 duration of Slags Poisoning on each of those times it bit me and the wound burned.
Looks like the Myers sampling kit may result in bonus leg drops. Having a tome of binding and no sampling kit didn't appear to have any special result.
