Overview -indoi-‘s Critical Assassin Guide
Hi Guys! I am returning player from Chaos/Odin pRO way back 2005-2008 with some know-how in Ragnarok online.

Currently playing in Loki server and I finally reached level 99 after grueling months of grinding.

Today I am going to share my personal knowledge and hope it will serve as a guide for other players who wanted to create an Assassin.

This guide is based on my own experience & understanding of Revo-Classic mechanics in ROPH.

Why Critical Assassin?

• Can reach 80% to 120% critical rate without the use of Soldier Skeleton Cards.
• High single-target DPS that can reach 1- 1.5k critical with high Aspd.
• High flee rate and can solo most of the monster in RO.
• Very effective for solo and fun to play.
• You need a lot of cards (racial critical cards)
• Requires endow to maximize its full potential
• Mediocre in MVP.
• Hard to level 99 compared to other Assassin Builds/Class

Since ROPH is running in revo-classic setup one must understand how stats works in this server. You may refer to for further reading.

Str: is your primary stat and should kept high to achieve a good DPS. You should have a minimum of 90-100 un-buffed Str or 110 using Str cards and food.

Agi: is your secondary stat which boost both your Aspd and flee. Aspd should be your main focus. Reaching 182 to 185 Aspd (Buffed) is the ideal sweet spot.

Vit: 9-40. IMO Vit doesn't really give you a high amount of HP but if you play WOE higher health pool is definitely needed.

Int: Leave it at 1.
Dex: Since you will have high critical chance, leave this at 1.

Luk: 40 to 60 is good but very wary that there are monster with high critical shield thus effectively reducing your critical chance. Luk also adds ATK and Hit Rate.

The actual ASPD calculation depends on AGI, DEX, ASPD Potions and skills, the type of equipped weapon, and current job class. It can take between 1 and 20 AGI to increase ASPD by 1.

I suggest you use stat calculators like this:
(I personally use this one)

Equipment: (Non UPG and High End Equips)

  • Jur [3]: It is best weapon for critical assassin especially with racial critical cards. Jurs has 3 slots and very easy to upgraded to +7. Try to get +8-9 for maximum efficiency.
  • Katar [2]: Higher damage than Jur but 1 less slot.

  • Indonesian Beret: +3 to All Stats
  • Pecopeco Head Band: +5% Increase ASPD

Weapon Cards:
  • These cards should be your main priority and you need 3 of each on your weapon.
  • Each card gives +7 Critical on Target Race + 10% Critical Damage.
  • This is the key in getting high critical damage and critical rate against monsters.
