Dal Shabet

Well, essentially, he could have retreated or "left the battle" and then simply reappeared under a spell and killed the enemy in the style of Adrian. NPCs can certainly perform the same actions as player characters, provided they have the appropriate ability. And searching corpses and a room isn't a matter of seconds anyway.

When the monster paused, Adrian aimed and shot it in the head, preparing to flee if the creature survived, and anticipating the following possible scenarios:
Scenario A (the best): it will die.
Scenario B: it won't notice the shot.
Scenario C: it won't leave the cave.
Scenario D (the worst): it will eat him.

The bullet hit the monster right in the head, but it didn't have the expected effect: the creature wasn't going to die. Now it looked even angrier than before, but for a while, it couldn't move due to the damage it had sustained.

A funny fight. It started at a short distance, and the rogue wasn't slower than the archer. If he had even 1 more point of strength or if Taola didn't have quality arrows, he would have probably defeated her now.

Taola misses.
Taola deals 40(-10) damage to the rogue (120).
The bandit leader deals 38(-10) damage to Taola (52).
The bandit leader deals 38(-10) damage to Taola (24).
The bandit leader misses.
Taola deals 40(-10) damage to the rogue (90) and paralyzes him.
Taola deals 40(-10)*3 damage to the rogue (death).

And although Taola managed to defeat the assassin, she couldn't help her master in any way. If she had any medical knowledge, she could certainly have prolonged his life by an hour or two, and with a medical kit, she could have even saved his life, but she had none of that. Ratislav lay unconscious, and his body was rapidly approaching death.
