Vanilla Rpg Classes: The Warrior

Heyo!
I'm comin' at ya with some epic programming in an opaque bottle wrapped in gift wrap stored in a file that we insert into the minecraft save file to gaze upon the beauty of it!
All the time I am just working on programming rather than building. I'm more of an engineer than an architect :/ So I thought:
"Hey! People loved my first vanilla classes! I have four new updated versions that are in an Rpg that is failing before my eyes, and are completely enjoyable!"
So then I slapped a patent on it and called it mine. Thanks Thomas Edison. Patenting things that were yours (and not yours too. :/ Epic invention thief xD) since the mid 1800's.
But all that aside, yes, this is the first of four classes that are in the Rpg I was trying to achieve.
I've been given letters about the amazingness of the classes and the mechanics, so it is my inspiration to give the classes to you ;D
The Warrior is a powerful class that focusses on mostly Offense.
It, like every class I will produce, has four unique abilities to enhance the capabilities of that said player.
The abilities are as follows:
Blood Thirsty: Heals you for every time you deal damage.
Rage: Puts you into a raging fit for five-ish seconds.
Unnatural Endurance: Hardens your body like stone.
Smash Attack: Flings your opponent away! (Just like Smash Bros!)
All the inner workings are yours to have, just if you use the programming in a map or showcase or the like, make sure to drop some credit.
Make sure to Diamond and Sub if you want some all around cool stuff. I'll be putting out the next three classes soon, and even more.
(Get excited, I'm planning a Blood Mage class ;) )
Can't wait to show you more guys ;)
