Better Safe than Sorry is a hidden combat achievement for beheading an enemy with Artery Strike while they suffer from Burning Blood. It relies on a random decapitation, so expect a few tries.
1. Learn Artery Strike from the Swordmastery manuals and unlock Burning Blood. 2. During the day, hex an enemy with Burning Blood. 3. Make them bleed. 4. Finish them with Artery Strike and hope for a beheading.
The beheading is a roll, not a guarantee. Quicksave before the fight and reload until the head comes off. Weaker human enemies make good test targets.
