A summary after killing ~ 95% of all bosses:
This is From Software's latest challenging game after Dark Souls and Bloodborne. Some people think it is harder and vice versa, but it's just to be persistent so you can kill all bosses in the game, maybe not the electives.
Of the game's bosses, about 70% are "minibuses," which you can almost always remove 50% of life by doing a "Stealth Deathblow" before you attack them. In rare cases, these can be performed in battle. Many bosses have a specific weakness, be attentive.
Unlike their previous games, you can't rely as much on ducking the enemies' attacks without much focus on mating and taking the initiative, sometimes jumping to avoid sweeping attacks. Stamina has been replaced by Posture and unlike previous games, this resource is filled up faster while blocking. However, in order to pair, you must click on the blocking button just before you get hit.
Finally, an explanation of what happens when you die. When you die, you lose 50% of your money (spend!) And experience to the next level. There is a 30% chance that this will not happen, "unseen aid". If you die too often, it can have negative consequences, which means that you cannot temporarily make assignments for individuals in the game and that your unseen aid is weakened. This can be cured and I recommend doing it after every "main boss". If you revive yourself in battle and do not die then there will be no consequences.
