FOR HIGHRER LVL SURVIVORS Let IT hold you in its mouth, once it has done this shoot trang darts at its head. Since they have low torpor it will KO easily. They also don't have an oxygen bar, so if it KOs in the water that's no big deal unless there is sharks. The lower lvl ones are usually near the outskirts of the swamp
Here’s how I did it.
Step 1. Find low lvl Kapro
Step 2. Run at Kapro
Step 3. Punch Kapro til it faints
Step 4. Shove boa meat down it’s throat
This method worked twice for me, with a lvl 1 and a lvl 3. If you’re going for a high lvl, a crap load a health will see that this method still works
