Hey, I have a really good mage that is unstoppable without all the armor and strength that most mages use. Here is what I would recommend using.
Equip Skills;
Blast: 1 since you'll need to use it a lot and the damage really doesn't matter. Get it to 10 later if you want max effect.
Meteor: 10, very useful for strategic reason.
Stone Grip: 10, sounds dumb and weak but it's actually really useful if you use it right. It slows down the enemies as well as damages them pretty well. I will explain this later.
Stats: 2/3 of your stat points should go towards Energy, and the rest should be put into Endurance. It works really well, and damage is till pretty good.
Gear: Get this in order: Mp Regen, Mp, Energy, Hp Regen, Hp, Endurance, Attack Specials, Defense Specials
Passive Skills: Use Magnetic Shield, Artificer, Channeller, Spell Mastery, and another of your choice. After you've reached Level 75 maybe drop Magnetic Shield for Energy Manipulation if you want more damage with meteor.
STRATEGIES: This is the most important part of this build, because if you don't know how to use the three skills, they're useless, once mastered, you're unstoppable.
Fast Enemies: Take a mob of goblins for example, just use blast once or twice to sweep them all off their feet, then use stone grip to finish them off, you can throw in meteor if you'd like but not needed. For a fast and strong enemy like a Goblin Slayer, just spam meteor and brace for some damage. You can also do this with meteor but it doesn't work as well since the enemies do get up and start moving again and they can avoid the max AoE. Stone grip slows them down and attacks at the same time, allowing you to use any other type of attack in there to assure the kill, plus if they escape just use blast again to blow them back to AoE of Stone Grip. Also this takes some practice but you can strait off use Meteor to where they are heading, it will do good damage but it is hard to aim.
Slower Enemies: Use Meteor until they die, use blast if they get too close and use Meteor again while they are down. 100% Kill.
Tough enemies: Sub-Bosses, they are usually slow, just spam meteor like you would do with a zombie.
Campers: Now THESE ARE THE MOST ANNOYING ENEMIES IN THE GAME. There will always be those Mages or archers hiding in the back of a mob that will stun you with their ranged attacks. Now since they are usually not alone, you cannot take them out first, unless you want to take a massive amount of damage. When you see these, use blast to knock all the enemies down first (Since they usually summon weaker enemies) and hail some meteors on them. If they are with a Sub-Boss, brace for some trouble and kill that Sub-Boss first, if they are with a boss, kill the mages first. Always use Meteors on these campers because they don't usually move. Tip: If you can, try to get close to them, there are glitches in the programing that makes them stop attacking you when you are close. I tested this many times and I found that you can even punch an archer or mage to death.
Circle of Enemies: When they have you surrounded, use a Faerie, OR summon Stone grip to where you are standing, this will give you some time to summon Meteors all around you. A wind Faerie is much better because it will 100% blow your enemies back a little, just enough for you to get out of there.
Mix of enemies: Take them in order: Faster enemies, Sub-Bosses, Campers, Slower enemies.
Here are my skills at level 75:
Blast: 10
Artificer: 10
Spell Mastery: 10
Channeler: 10
Energy Manipulation: Not needed but 10 anyways.
Stone Grip: 10 or Nightmare: 10
Meteor: 10
Last 4 points should be invested in pots, gotta have em pots.
How To Use This Build
1: Stay [b]AWAY from enemies, get them from far away. The two attack spells you have have a slow cast lag, so always open with a blast when you can and when they are at a distance, wipe them out.
2: Just like all Mage Builds, Mob Control is key. Try to keep all enemies on one side at all times. If you maintain that, you will for sure keep your potion use to a minimum, I hardly ever use potions unless I become surrounded.
3: Equipment, get as much MP/Mana Regen in all your armour. And don't worry about your staff, your staff should have 50% change of stun and 50% chance of Push/Slow so it will always do a side effect with each staff attack. Since a mage's base attack sucks, this can be very helpful.
4: Spamming Meteor does a great amount of damage, and when you are not moving and you are simply spamming the button assigned to Meteor more then 20 meteors can come flying down. Good in boss fights. if you are doing this you will need to use potions.
5: This build is all relied on MP REGEN, not your total amount of MP, because your attacks do cost a good amount of MP, so recovering is better than a good stock. Mp bonuses in gear is still good, just get MP REGEN first, while keeping your MP stock just over 1800MP, won't really need a lot more than that.
6: If you are using the Blast/Nightmare strategy, you will find that Meteor will no longer be used as much and mana will run out faster. For this mana heavy spec maybe drop Sorcerer for Prophetic, and get all that MP/Mp Regen in there. Good luck!
