Battle Wizard(Alpha 3.0)
Battle Mage has a play style that is very different than other ones. You will need very specific perks and gear for it to work.
Armor and Weapon
As a starter you do not need anything fancy and you can do this build with a little bit of gold. First of all you will need a Crystal Ball and Rondel] Dagger which are purchasable through Alchemist and Weaponsmith respectively.
Perks and Skills
As a standard we are going to be picking Meditation for regenerating our spells and Spell Memory to cast those spells. When it comes to perks we have Arcane Mastery, Quick Chant, Ice Shield, and last spot is flexible but I recommend Reactive Shield for a little bit more defense. Make sure to use your Meditation in spots where you will not be spotted!
Spells
We are going to be taking Magic Missile, Ignite, Haste, Invisibility, and Fire ball if you ever end up finding more spell capacity. Note that you can interchange fireball and magic missile depending on your preferences. I chose magic missile since it synergizes well with ignite.
Play Style
It is extremely important that you gather information about the opposing team. If you are solo you need to play in and out style like a rogue. However, if you have team mates you can go in take one and leave causing disruption while your team pushes in. Your main weakness will be close range high damage dealing classes like Rogues and Barbarians.
As an engage you need to use Haste -> Ignite -> Invisibility and sneak to their backline and hopefully pickup a cleric, mage or a ranger kill. Then quickly cast another invisibility to flea to safety or continue attacking their backline depending on their team composition.
When it comes to dealing with enemy mini bosses you can use Ignite + Magic Missile combo to deal a lot of damage.
You can also play as a support mage buffing your team mates with Ignite and Haste.
