How to achieve Life Lock on Diablo 2?

To achieve Life Lock in Diablo 2, you need to equip items that provide the "Life After Kill" bonus. This can be found on certain gear, runeWords, or charms. Additionally, maximizing your character’s survivability through proper skill allocation, defensive gear, and strategic gameplay will help maintain your health during battles, effectively locking in your life. Always have a plan for healing items as a backup, as Life Lock is susceptible to damage spikes.
