Using katar on ragnarok online PC double your chance of striking a critical,luck increases critical rate and perfect dodge,dex was a useless stats on ragnarok to assasin since critical assasins have a critical rate near ´´100 %´´ ,but dexterity increase chance to hit and minimal damage. A critical strike on ragnarok means that your atack pierce the enemy ´´defense´´ from equipment and also that the atacks hits(obvious). You have in this game two defenses, the vitality defense and equipment defense,for example: a monster atacks you pysically and cause 120 damage, but you have 30 vitality defense and 50 equipment defense, that means that the atack of this monster will be reduced like 120/50=60(equipment defense means the percentage that the atack will be reduced) after the equipment defense enter the vitality defense 60-30=30 so you will take 30 of damage. Inteligence and magic defense works as the same relation beetween vitality and psycal defense. All classes when they level up their base level they get a bonus of 1 to dodge and the chance to hit. I am still trying to get this game, i played ragnarok online a long time ago on Brazil but i need some help if what i said also work on this game.
Someone help elelement above because all my knowledge is base on ragnarok Online PC.
Assasins on the pc version could only hide on tiles nears the walls and they also have increased movement speed while hiding, they could also do a skill called grim tooth when in hide mode but grim tooth cost so much sp to do litle damage unless you are a cross assasin really strong and have some blue potions with you.
