The upper limit of health was very important.
It could allow the players to withstand higher damage and have more room to operate.
For example, fighting and retreating, taking healing potions that had good healing effects during the battle, and then recovering the damage he had just suffered and the health he had lost.
It wouldn't be bad to the extent that he would be directly beaten until he had low HP and wouldn't even have a chance to recover.
And usually, this high damage caused by the enemy was done by a relatively key skill.
Under normal circumstances, the cooldown time for such a key skill would definitely not be short.
And at this time, as long as one recovered their health points, they could relax and be as bold as they wanted in the following battle.
Without so many shackles, it could clearly greatly increase the probability of victory in a battle.
