I am experimenting with a modification to the backstab mechanics: it is possible to backstab only if the enemy’s health is below 50%. When it is possible to backstab, an icon appears on the enemy’s health bar indicating that it is possible to execute a backstab on the enemy (this also applies to frontstab).
I am introducing this to decrease backstab abuse and increase face-to-face combat. Also, backstabs refill potions, so it’s something that should balance the potion refill mechanics.
