Spamming Ranger

Skills
Apply Poison, Onslaught, Screaming Shot, Power Shot, Called Shot, Needling Shot, Whirling Defense, Pious Restoration
Runes
Anything that will add to Marksmanship and Expertise. Expertise is good for making the build work as a spamming build, but marksmanship makes it easier for the true use of the build to kick in.
Weapon
Anything with an Enchant Plus 20% Preferably. Vampiric Bowstring is also very very nice with this build. Though I am hoping someone tries this with zealous, it might work really well, but I havent tried it.
Usage
Onslaught is a Dervish Elite that reduces Attack Skills energy cost and recharge time by 25 percent. The concept is to add this on to the Rangers Expertise allows for energy reduction of somewhere in the range of 60-70 percent easily. Done correctly you can spam power shot and such for 3-4 energy each, and they recharge quickly.
What makes this build powerful though isnt the power shot and other moves, it's actually needling shot. Once someone reaching 50% health, needling shot recharges instantly. Now, normally you can only spam it so much without crying for energy. With this build you can spam needling shot, which does armor ignoring damage for 2 energy each, and its a quick attack time. So imagine they reach 50% health, and suddenly you can always hit 25 damage constantly on them, without energy issues. It adds up fast. With a vampiric bow, thats also alot of health from them going to you. And if you have poison and bleeding still, they still have degen.
As for blocking opponents, thats the time to spam called shot.
Weaknesses
Standard Warrior Weaknesses, actually. Blinding, or anything that reduces chance to hit. Blocking, even with called shot, can be an issue since you cant use very strong moves anymore. Healing will bring opponent above 50 sometimes, so it can ruin your flow, so be careful of this. And the biggest issue is spiteful spirit or spoil victor, and moves like that, they kill you fast. Also the standard enchant removals.
Also, make sure, MAKE SURE, to notice when your Enchant runs out, you will suddenly drop to no energy if you try and spam without it on. Also be warned, Pious restoration will remove Onslaught, so use it sparingly.
Otherwise, this is a fun build and can kill things very quickly if used right. Good against bosses seeing as it is rather straight forward, making it something you might want to have a real purpose for.
