Thief can't use Horn of iceberg if they got "SFD" or "Protection"
Just like warrior can't use Dark Blade after they got "SFD" , buy they can start DB before got SFD~
In another word , thief can use Horn of iceberg only under these state:
1. no buff
2.CancleFromCounteractionOfDivine (ignore curse magice include LifeDrain,but no physical Defence power)
3.DivieBless (ignore curse magice,but no physical Defence power)
4.icing Armor (Physical Defence power,buy will attack by curse magic)
After these correction ,Horn of iceberg still ignore most defense magic , but~~
you will not see a thief got "SFD(Pro)+ac22x+eva33%+smart33%" and keep use Horn of iceberg but superhard be killed
and
you will not see a warrior got"SFD(Pro)+ac22x+smart33%+CA41%" and keep use Horn of iceberg buy superhard be killed
