Brewing Question

[Seth~]

I am on the lower tier of the ranking list (but that is another issue) My gears:

Hat - luck O Irish Hat, Nobility Gem, HeRO advanced backpack
Armor - Diablos Armor +3 luk (baby leopard card)
Weapon - Excalibur
Shield - buckler(zherlthsh card)
Garment - Morrigane's Manteau (I broke my +9 garment with a Chung E Card)
Shoes - Crystal Pump
Accessories - Navel Ring, Glorious Rublic Ring

As said

Job level helps a lot, as well as having the right skills (Pharmacy and Learning Potion) and a Vanilmirth with the skill Change Instruction.

Maybe this link also helps you a little: http://ratemyserver.net/brew_calc.php

You can also get stat foods (luk,dex then int)
During brewing party you can also get stat assistance:
Quagmire (in pvp) then Marionette Control (with a int & dex based player), then bless & gloria.
You can also activate curse similar idea as with quagmire but have not tried that.
A Deviruchi pet. Other pets might give more bonuses but dono.

Get more advise from Kittie and/or get a guild backed God Items.
