@PoweredDragon Mogłbyś mi zrobić przykład na 2 itemy? Hełm o nazwie "Hełm" z lore "Obrona: 1" daje obrone 1,  klata "Klata" z lore "Obrona: 20" daje obrone 20 resztę ogarnę sam. ( oczywiście itemy nie mają się świecić ) 
 

Zrobiłem ogólnie.

Jeśli całym opisem przedmiotu jest Obrona 1 to przedmiot daje obronę 1, jeśli jest 2 to daje 2, i tak do 4
Jeśli chcesz więcej, to musisz mi powiedzieć, będę musiał to zmeinić

@PoweredDragon Zrobiłem takie coś i nie działa, dobrze zrobiłem ?

on damage:
  set {_EPF} to 0
  loop 4 times:
    lore of victim's helmet is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    lore of victim's leggings is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    lore of victim's chestplate is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    lore of victim's boots is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
  set damage to damage * (1 - {_EPF}/25)
command /helm:
	trigger:
		give diamond helmet named "Elo" with lore "&4Obrona 18" to player

Tak, dobrze zrobiłeś. Ten hełm powinien działać jak hełm z prot 18  Tylko trzeba lekko zmodyfikować przelicznik, bo prot 18 nie jest uwzględniony w skrypcie pierwotnym

on damage:
  set {_EPF} to 0
  loop 20 times:
    lore of victim's helmet is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    lore of victim's leggings is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    lore of victim's chestplate is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    lore of victim's boots is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
  set damage to damage * (1 - {_EPF}/100)

@PoweredDragon jak mam założony hełm to zadaje 2 serca, i jak nie mam to też więc nie działa ;c

on damage:
  set {_EPF} to 0
  loop 20 times:
    lore of victim's helmet is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    lore of victim's leggings is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    lore of victim's chestplate is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    lore of victim's boots is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    {_EPF} < 20:
      set damage to damage * (1 - {_EPF}/25)
      stop
    {_EPF} < 40:
      set damage to damage * (1 - {_EPF}/50)
      stop
    {_EPF} < 60:
      set damage to damage * (1 - {_EPF}/75)
      stop
    {_EPF} < 80:
      set damage to damage * (1 - {_EPF}/100)
      stop

Teraz spróbuj

@PoweredDragon Normalnie 3,5 , z hełmem ochrona 18  - 3 serca, gdy założe normalny hełm ochrone 18 z komendy to tylko 0.5 więc coś nie działa

Obstawiam, że wziąłeś starszy kod, który był źle zrobiony. Wyżej jest poprawiony, który powinien działać już dobrze

@PoweredDragon Wziałem ten najnowszy kod co wysłałeś, nadal to samo 3,5 serca z hełmem 3, raczej protection 18 tak nie dziala

Wszedłem na wiki, żeby sprawdzić przelicznik; wynika z tego, że:

Using this method, a player could give themselves, for example, 
a full set of diamond armor with a Protection V enchantment on every piece. 
Following the algorithm above, we find that, since Protection V has an EPF of 5, 
the armor will exactly reach the maximum EPF of 20 for all types of damage. 
Any higher Protection enchantments could be used to allow the cap to be reached with only one enchantment, 
rather than having a full set of enchanted armor, but would be wasted if all pieces shared the same level enchantment.

Czyli, że jeśli nakładamy na cały set proection > 5, to nic to nie zmieni, bo i tak już osiągniemy max redukcji obrażeń

Czyli ten skrypt:

on damage:
  set {_EPF} to 0
  loop 20 times:
    lore of victim's helmet is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    lore of victim's leggings is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    lore of victim's chestplate is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    lore of victim's boots is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    {_EPF} <= 20:
      set damage to damage*(1 - {_EPF}/25)
      stop
     set damage to damage*0.2

@PoweredDragon Nadal prot 18 i 3 serca wali, ale wezme helm prot 5 i wali 2,5 serca. Czyli nie da rady zrobić powyżej prot 5 ?

Dać radę da, gdzieś jest błąd, którego w kodzie nie ma k_k

on damage:
  set {_EPF} to 0
  loop 20 times:
    lore of victim's helmet is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    lore of victim's leggings is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    lore of victim's chestplate is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    lore of victim's boots is "&4Obrona %loop-number%":
      add loop-number to {_EPF}
    loop 4 times:
      set {_Q::%loop-number%} to {_EPF}/25
      set {_Q::%loop-number%} to {_Q::%loop-number%}/loop-number
      set {_Q::%loop-number%} to 1-{_Q::%loop-number%}
      set {_eEPF} to 20*loop-number
    {_EPF} < {_eEPF}:
      set damage to damage * {_Q::%loop-number%}
      stop
