Thanks to everyone who have commented on this guide over the years! Hopefully you guys will like my new guide just as much as this one!

I meant Thara/Horn of set 1.

For BG or PvP

Set 1: instant-cast, more reduction gears (ideal when attacking, or with few support such as Palladins or Clowns)

Headgear:
I love china (+3dex 10% demi-human resist, if not available any +3/4 dex headgear)
Robo eye
Well-chewed pencil

Weapon:
Warlock’s battle wand (other BG rods suck)

Armor:
Mage BG set (enchanted with +3 dex)
w/ ED (Marc is better but I needed 1 more int), Salamander (Noxious for switching), Matyr cards
Valk shield w/ Thara frog/Noxious card

Accessory:
2 Orlean’s server w/ Zerom card

This set with +7 int/dex foods and Box of Gloom allows me to reach 150 dex (instant cast) and 140 int

Set 2: Pure Damage (ideal for defense or whatever side as long as you have at least a Clown to support you, better if devo’ed)

Headgear:
Crown of deceit (+4int -10% cast time) w/ Isilla card
Rainbow scarf (+1 int)

Weapon:
same

Armor:
BG set (enchanted with +3 int)
w/ E.crothen card (+10% matk), Salamander, Matyr

Shield:
+10 Book of Charms w/ Thanatos Despero card

Accessories:
same

With +7 int/dex foods and Box of gloom, allows me to achieve 155int/140 dex. With amplify magic, you often wipe more than half of the enemies stack with 1 SG, and if precasting with MS enemies drop to the floor very quick.

Both of these are not for WoE, just BG/PvP if you want to rack up some kills.

It’s certainly been a while since I’ve played RO (3rd job really didn’t wow me…).

Still, I’ll try to correct as much as I can for your build.

int : 99 (I always kept a High Int because I kept people out-zoned with Sight Blaster and Safety Wall. I totally approve of 99 Int. ;D)
dex : 99 (You know, I went between keeping this at 93 (Contrary to the build I put above) because I didn’t mind a tiny speck of time. Zoning allowed me to keep it a little lower.)
vit : 20 (It’s always good to have Vit. I liked it closer to 40 just because I hate being so squishy.)
str : leftovers (NEEDS MOAR POTIONS!1!11!! I approve.)

for equipment :
+6 diablos set with cards needed in battle (Err… not sure what cards you’re talking about, but if you’re doing a typical WoE set, I’m guessing (Marc or Evil Druid), Green Ferus, and whatever is your preferred Mantle card.)
+6 staff of destruction [Hill Wind] (I wouldn’t put such an emphasis on Jupital Thunder. Consider putting in Drops instead. OR NECRO CARD WOOP WOOP)
+6 staff of destruction [Laurell Weinder] ( I love Storm Gust. :3)
+6 orleans server [Thara Frog] (>:3)
+6 apple of archer (The Oh-So-Useful All-Too-Silly Dex Hat)

Very good. Hope you continued to refine both your build and equipment. Good luck out there!

for equipment :
+6 diablos set with cards needed in battle
+6 staff of destruction [Hill Wind]
+6 staff of destruction [Laurell Weinder]
+10 staff [4x drops]
2x orleans gloves [Zerom]
+6 orleans server [Thara Frog]
+6 apple of archer
mainly i used +6 SOD [Laurell Weinder], but i also brought the equipment i mentioned above,
just in case the opponent is tough enough :D

anyone would like to try my build, be my guest
