here is my question what bonuses they give only better chance with % enchants or can put more elemental than normal armor ?
i have enchanted a blessed immortal l. boot and it gives normal p.def (+3p.def for each enchant). so your anwser is not valid, or the server have this items bugged.
in the korean powerwiki it says that blessed items have a 50% increase enchantment effect,doesn't say if from +4 or +1
and u get some extra benefits when u enchant more than 4+ for example immortal shield +4 increases its shield def power
that applies to all armors not only to blessed.and i don't see anywhere anything about shield. http://www.lineage2.com/en/game/patch-notes/goddess-of-destruction/new-items/ also these increased stats appear in status window not on the item info.
blah you get 50% more effects on enchants, starting from +1. from +4 on, you get additional bonuses as stated on the item itself.
as said before: i have enchanted a blessed immortal l. boot +1+2+3 and it gives normal p.def (+3p.def for each enchant).
did you read the description on the ear?it says it gives 2 pdef per enchant.so yes you get a 50% bonus.
