Today, Valve has revealed the addition of Terrorblade to the roster. He's that friendly looking fellow at the top of the page.
Here are Terrorblade's abilities.
Conjure Image - Summon forth an illusion of yourself to aid you in battle.
Metamorphosis - Embrace the darkness within, trading your melee attack for a ranged strike while granting additional damage.
Sunder - Sever the soul of an ally or enemy, exchanging your health for theirs.
With the addition of Terrorblade comes some new cosmetic items for him. If you purchase any of these during the New Bloom event, you will get an "Exalted" quality on the item.
Deep in the hell of Hell, Terrorblade lay bound behind fractal walls, sentenced to an eternity of twisted contemplation. He stared long into the reflection of his own worst self. And long did his worst self stare into him. Now they rise together, a single entity more powerful than ever before....
When equipped, this item grants these custom upgrades to Terrorblade:
Several new animations - Altered voice - New base skin & model with special ambient effects - New Hero icon, portrait, loadout pose & minimap icon - New spell effects and icons - Socketed with a gem that tints the coloring of Terrorblade and all of his abilities - Custom death effect for Terrorblade's victims
The Arcana is arriving on February 6. The upcoming 6.80 update will also include (among other things) a Random Ability Draft. At level 11 you can enjoy this mode that finds each player randomly being assigned a hero. Each hero's abilities are placed into a pool as each player then takes turns choosing which abilities their hero will bring into battle. Yes, that means that heroes will be using abilities not native to their character. I'm sure that will make for some interesting times.
