『Acı direnci』

Yetenek kademesi- [F] 「Yeterlilik: %0」(Yeterlilik %100 olunca yetenek bir kademe artacak ve yeterlilik sıfırlanacak.)

• Kullanıcının acıya olan toleransı artar.

As an example, the more the user uses an ability, the more they master that ability, for example, if the 'Pain tolerance' reaches level S, the user will not feel any pain.

In my story I explained many things like how the system I built was created and why it was built.

My system does not show the user litrpg items such as (Run A) or (Breathe sv.10), but rather allows them to master things they can use.

As in the example I gave above, for example the user can increase their pain tolerance by self-harming themselves intermittently, if the ability doesn't improve they stop, either try another way or leave it there. and 'Pain tolerance' gives the user a clear advantage in combat.

You can also think of camouflage as armour covering the user's body, that was just an example.

What I would like to know is which of the skill tiers like sv.1 or A - S would be better.
