It is just another troll game that does not know anything about DnD game. I played a lot of DnD games like Baldur's Gate, Pillar of Eternity and I enjoyed them, but in this game, they created an unusual mechanic to the game and it makes your attack always miss and the enemy never miss. Ok you need to take weapon proficiency to increase your attack chance, but in my playthrough it does not give anything. My party always misses every attack but the enemy can hit you with Critical Hit and deal 90 damage.
If you don't believe me about the attack miss situation, you can google it and you can find a lot of people complaining about this.
If you want DnD, go play Baldur's Gate, Pillar of Eternity, Planescape Torment, etc
