Ragnarok Crusader Build Guide

Shield Charge – Stuns your enemy in a certain chance depending on the skill level. You may use this with status weapons tho give different status on your enemies.
Build:

Grand Cross build

Int: 99
Dex: 60-80
Vit: 50-70

Int is the most important stat in this build because GC (Grand Cross) skill depends more on the matk (Magic Attack) rather than the atk (Attack Power) of the character. The skill Heal also depends on the int value of the character. An equal distribution of dex helps the crusader to cast GC faster, therefore fast kill. A fair vit helps you survive on mobs of monster while leveling.

Skills:

Grand Cross – This is the most important skill for this build. Level 10 is recommended
Heal – Don’t go out without it =)) you need RO Zeny this to aid your self on mobs and after casting GC on the enemy. Level 10 is recommended.
Faith – Gives you 2000hp and 50% resistance to holy attack at level 10.
Other skill points are distributed as a prerequisite skill in order to use GC and Heal
