Angeling Carded armor will bestow Level 1 Holy Element to your character. This is the same exact effect as having B.S.Sacramenti or the Royal Guard's version, Piety. First off, visit this iROwiki article:
http://irowiki.org/wiki/Holy
This means the following.....
-A Holy Element monster (let's say... Angeling! a Holy 4, Angel Race) hitting you with its normal swing will not be reduced. The skill Holy Attack that it uses WILL be reduced (it will miss, to be precise).
-Using Grand Cross while being Holy is great, and negates a large chunk of sacrificed HP (won't get into the specifics of GC lol) but those evil Shadow/Demon/etc monsters are gonna do more dmg with Shadow attacks :<
-Archbishop attacking with Adoramus will completely miss a Holy player
-A Ranger in WoE that Arrow Storms you with Silver Arrows will miss you. If they pop a Cursed Water, they will do an extra 25% dmg! If a Priest class uses Aspersio on the Ranger, they will miss until they reconvert/arrow/bow switch.
-A Royal Guard with a Long Horn equipped (Holy property spear) but using a skill like Earth Drive (deals Earth property melee dmg) will be reduced by 25% to a Holy element player.
Being Holy also pairs well with Deviling Card's elemental dmg punishment, but shadow attacks will really hurt, be careful~
On a Crusader class, you can also attain Holy element by equipping all of the Crusader card set (Archdam, Freezer, Heater & Permeter Card) if you want a cheaper way to test it out. :3
