About Gears:
First priority in gearing is becoming immune to stun. If you're not stun proof, you're going to be useless in WoE. There are a lot of ways for people to inflict stun effects on you Arrow Shower or Sharpshoot from Snipers, Scream from Gypsies, or Meteor Storm and other spells from High Wizards (because of the BG Wand). If you cannot afford/the server doesn't have a Holy Marcher Hat, a +5 Dark Bash with a Stalactic Golem Card will work fine. Aim for 149 DEX because of how RO mechanics are, 150 will have more delay in between casts than 149. High Wizard gears have minimum options. You want Salamander because Meteor Storm is the best DPS skill. Marc is used when you have a Mind Breaker to give you more damage. Evil Druid is useful when you're under Mind Breaker and want more damage, or simply don't have a Mind Breaker. If you want more INT, you can opt to use Book of Charms. If you wan't more Attack Speed, you can opt to use the Thorn Shield + Horn of the Buffalo. You lose DEX but gain more Attack Speed which allows faster casting. Remember, you can build glass-canon because if you get Dispelled, either way you're dead.

Stats
STR : Left Over Points
AGI : Base 25
VIT : 1 Vit Always
INT : Base 99
DEX : Base 99
LUK: No
About Stats:
You want as much DEX and INT to be able to cast Meteor Storm and deal a lot of damage. All left over points go to AGI because more AGI equals more Attack Speed, which means you spam more Meteor Storms.

Gameplay
Like the image above, you want to be behind the DD Creators and FS Scholars. You want to be hidden from being dispelled because of how squishy you are. You want to cast Meteor Storm on front of their Land Protector over casting it on them. Casting it in front of them still allows you to damage and kill their DD Creators without exposing yourself to being Dispelled resulting in death. You want to refresh buffs as much as possible (When you no longer have it.) If your guild is pushing, you should also push, but still be behind your front-line. At this point, using Jupitel Thunder to get rid of the other DD Creators is top priority before proceeding to cast Meteor Storm on top of their stack. Be sure to carry Crystal Fragments and get Link. A High Wizard will die if his magic is reflected back to him, being linked with Crystal Fragments removes that. Only 1 person in guild should Storm Gust, and that shouldn't even be amplified because he should go back to Meteor Storm right after.
