Life leech is your life's blood. Without it you die.
Stamina leech is almost as important. Your swings slow, your life leech slows, you die.
Mana leech isn't as important. You'll be leeching back enough mana from Wraith Form to keep your specials and Lightning Strike going.
I'd recommend a weapon with Life and Stamina Leech. Hit lower attack would finish off an awesome weapon. You already have hit lower defense on your glasses, and your hit chance should be near max at all times with lightning strike.
Max defense chance (I mean MORE then 40%, more like 60!), and max your resists, or the resists necessary for your 'prey'. Get a quick ONE handed weapon with HLL, HSL, HLA, DI on it. Take 50+ refresh pots with you. Figure out your "break points" for swing speed. At what stamina your swing speed slows one 'click' and set it up to auto drink a refresh when you reach that level.
Utilize Lightning Strike all the time, counter attack all the time, and Evasion ONLY when you need it. Like when your stamina is taking a hit, use Evasion to get the potion drank. If you rely on evasion constantly, you will die because of the delay.
Try to NEVER run off to heal. You hit - you heal. If you run off, you'll get zapped while trying to Spirit Speak. Most deaths occur while running away. And these deaths could have been avoided if you'd kept calm, drank a TR and held ground.
I'll see about working that menu in sometime. The biggest issues I have are:
Some attacks are exclusive: if you select one, a different one must be de-selected
Saving the options and recalling them from a file
Recalling the options in the setup of the script
Enabling the menu without delaying the main loop of the script
