BIO
Storm Spirit is literally a force of nature--the wild power of wind and weather, bottled in human form. And a boisterous, jovial, irrepressible form it is! As jolly as a favorite uncle, he injects every scene with crackling energy. But it was not always thus, and there was tragedy in his creation. Generations ago, in the plains beyond the Wailing Mountains, a good people lay starving in drought and famine. A simple elementalist, Thunderkeg by name, used a forbidden spell to summon the spirit of the storm, asking for rain. Enraged at this mortal's presumption, the Storm Celestial known as Raijin lay waste to the land, scouring it bare with winds and flood. Thunderkeg was no match for the Celestial--at least until he cast a suicidal spell that forged their fates into one: he captured the Celestial in the cage of his own body. Trapped together, Thunderkeg's boundless good humor fused with Raijin's crazed energy, creating the jovial Raijin Thunderkeg, a Celestial who walks the world in physical form.

INTRODUCTION
Storm Spirit is considered a nuker, initiator, and disabler in DotA. Storm can move so fast like a lightning using his ultimate Lightning Bolt and then catch somebody and make him can't move and then kill him with Storm's nuke and attack.

Why maxed Static Remnant first?  This is your main nuke, you will need this for ganking, farming, and killing or early mid game.

Why maxed Electric Vortex before Overload? The longer the disable, the better for the team because the team gets more time damaging the disabled target.

BIO
Through a process of divination, children are selected for upbringing by the Sisters of the Veil, an order that considers assassination a sacred part of the natural order. The Veiled Sisters identify targets through meditation and oracular utterances. They accept no contracts, and never seem to pursue targets for political or mercenary reasons. Their killings bear no relation to any recognizable agenda, and can seem to be completely random: A figure of great power is no more likely to be eliminated than a peasant or a well digger. Whatever pattern the killings may contain, it is known only to them. They treat their victims as sacrifices, and death at their hand is considered an honor. Raised with no identity except that of their order, any Phantom Assassin can take the place of any other; their number is not known. Perhaps there are many, perhaps there are few. Nothing is known of what lies under the Phantom Veil. Except that this one, from time to time, when none are near enough to hear, is known to stir her veils with the forbidden whisper of her own name: Mortred.
INTRODUCTION
Mortred is a hero that have the biggest Critical Strike in DotA. She is a decent carry on late game. The critical is her trademark. On a late game she can deal more than 1000 damage in a blow with her critical. That's just too much for some squishy hero like Crystal Maiden or Shadow Demon and those squishy heroes will just explode like a small cockroach. Usually, Mortred player buy Bkb and Battlefury to make her get a cleaving attack. And with cleaving attack and magic immunity, nothing can stop her.
STATS

ABILITIES
1. Stifling Dagger
Deals minor pure damage and slows the enemy unit's movement speed. Deals half damage to heroes.
The first skill learned by the Sisters of the Veil often signals an incoming hit.
A single target, slowing skill that deals some damage. On early game, this skill is useful for last hitting the creep that too far to be attacked. With the low mana cost, this skill become spammable so you can use this skill last hits every time you need it.
This skill can also be used on a hero. This will make the targetted hero to be slowed and cannot run away from you so you can easily harass him. Don't try to be over-aggressive on early game, it is recommended to use this only for creeps for early game, and then if you need to gank on mid-late game you can use this on a hero.

2. Phantom Strike
Teleports to a unit, friendly or enemy, and grants bonus attack speed while attacking if it's an enemy unit.
Mortred's silken veil is the last thing her unfortunate target sees.
Jump into a unit, you can jump into foe to attack him or you can jump into ally to escape from enemies.
You get increased attack speed after you jump, a good speed booster for a carry that need lots of attack speed like you.
With a good attack speed, it will trigger more critical attack to demolish the enemy.

3. Blur
The Phantom Assassin becomes hard to see by blurring her body and disappearing from the enemy minimap when near enemy heroes. Some enemy attacks miss.

4. Coup de Grace

A divine strike, Mortred honors her opponent by choosing them for death.
The best critical attack in DotA. 450% damage on level 3 is no joke for anybody. With a decent damage on late game, this skill will provide you with 1000++ attack on late game. So if you can land some attack to the enemy, it is almost 100% that your team will win the game.

Why take Phantom Strike for level 1? You need Phantom Strike to escape if enemy wants to get firstblood by killing you. By jumping into nearby ally or creep, you can escape from firstblood.

Why maxed Stifling Dagger first? You need to increase this skill on early game for lower mana and more damage to last hit the creep. More level of this skill also makes you can harass more for enemy hero, with  more damage and more slow. Nuke is more effective on early game because enemy Hp is still low ( a few hundreds).

Why maxed Phantom Strike before Blur? Maxed Phantom Strike first gives many advantages because of the lower cooldown of this jumping skill. With lower cooldown you can catch your target by jumping and attacking him with more attack speed for every 5 seconds. You can also easier to escape if you are being chased.
