Thanks for your feedback! I think you didn't fully understand the game mechanics (which the game didn't mention, so that's my fault). Enemies have 2 types of health. Pistols deal damage to the physical type. When the physical health goes down to zero, the spiritual health starts to get used up, BUT it also adds a WOUND (blue circle), slashing it will kill the enemy instantly, pistols will lower the spiritual health for a longer time.
