New skills:
Blocking critical hits (Fast Reflexes):
You reduce the damage in each stage by 5% but you lose 3AP for stopping the attack a bit. You can only obtain this skill if you use a two handed sword or a shield.
Knocking enemys down:
If you hit an enemy with a heavy weapon, your opponent loses balance and loses 10% of his Block Chance for 3 rounds. The Chance of this event increases in each stage by 10%.
Stage 1: BC -10% for 3 rounds; 10% chance
Stage 2: BC -20% for 3 rounds; 20% chance
...
You can only use that skill with a heavy weapon.
Stab into the heart:
The enemy dies instantly. Chance increases in each stage by 3%. I think, a maximum level is required, because with only 30%, that skill appears quite often. I would suggest 3 stages for that skill. That skill can only be used with light and fast weapons.
Bone Breaker:
The Opponent becomes quite weakend after you broke his bones. With an increased chance by +5%, the enemy loses 40% of his BC and 30% of his AC.Here, I would also only suggest 3 levels.
Warrage: [more difficult for coding]
If you encounter multiple opponents, there's a 10% chance to kill one of your foes instantly
OR
You get +3 AP, so you survive easier such a challenging battle.
You should only be able to spend one skillpoint on this skill. Personally, I'm not so sure about the effects of that skill.
Bleed to death:
There's an increased chance of +10% to add the actorcondition "Bleeding Wound" to your enemy. The Magnitude also increases in each stage. Rounds stay always the same.
Disarm(similar to knocking over skill):
There's a 3% chance to disarm the enemy.He loses 50% of his BC and 70% of his AC for 3 rounds. That skill only affects humanoid npcs and there's only one stage aviable.
Beast of the wild:
You turn into a monster and can use your sharp teeth and claws to fight against other npcs. You can poison your enemy as a special ability. This character should be quite powerful but you can only use this ability for a limited time. You are able to increase the rounds of being a beast. That skill is extremely helpful for difficult boss fights. You start having 2 rounds=12 sec and then you increase the rounds by 1.
Paralysing:
You can paralyse your foe if he lost 50% health with a chance of 3%. There are 3 stages aviable with an effect of +2%.
Paralysing should weaken the enemy at the aspect Attack Points (like Stunned).
Surprise the opponent(Sneaking):
If you only use light armor, there's a increased chance of +5% that the enemy gets a critical hit with the chance of 100%.
You reduce the damage in each stage by 5% but you lose 3AP for stopping the attack a bit. You can only obtain this skill if you use a two handed sword or a shield.

As the reward for a quest seems to be a bit low, I would suggest learning skills as a recompense. Maybe you can unlock special fighting styles and so on. Or maybe you get +7BC/ +5HP/ +1DR... But only if your client is a fighter.
I'd really appreciate reading small in-game books. There has already been the suggiestion of a note in which the mysteries of the extraordinary and legendary items is described. Maybe Mikhail gives you a note of how to play
. Some other examples for storys: oegyth crystals/ actorconditions/ how to get fast money/ thieves guild/ catacombs/ Flagstone...
