Ursa

Ulfsaar the Ursa Warrior (or simply Ursa) is a melee agility hero whose abilities' main focus is the increase of autoattack damage, allowing for some of the most impressive sustained damage in the entire game.

He specializes in increasing damage against one target. His abilities allow him to attack at up to maximum speed (400 IAS) and gain bonus damage with each consecutive hit on a single target. With these abilities—Overpower and Fury Swipes—Ursa can savage beefy targets for as much as 700 damage per hit. He is a ferocious jungler and straightforward attacker, able to solo even Roshan at low levels if he has Vladmir's Offering or another lifesteal. Ursa is a carry who can snowball if he is farmed, but the array of anti-melee abilities existing even by the early game and his lack of any counterspells, especially to strong nukers and heroes with the ability to evade him make him a hero reliant on other spells on his team. Although an agility hero, Ursa's strength gain makes him very durable, and his ultimate allows his damage to scale by building strength items.

Tips

 * One level in Fury Swipes and Vladmir's Offering (or Wraith King's Vampiric Aura) allows Ursa Warrior to solo Roshan relatively early (as early as level 1 if the player gets lucky with Roshan's bashes). However, it should be noted that Fury Swipes is a Unique Attack Modifier and, as such, lifesteal effects that are also Unique Attack Modifiers (such as that from Morbid Mask) do not grant lifesteal, as Fury Swipes overrides them.
 * As a hero with little natural capability to forcibly engage combat, speed items such as Phase Boots are useful for chasing down heroes while patrolling alone.
 * Earthshock is a relatively effective slow even without Blink Dagger, but regardless of the circumstance, initiation is best left to allies due to its short range. It is best used instead to prolong the time enemies are in range.
 * While small, Overpower does have a cast time and should be cast preemptively to prevent time lost in the middle of a fight. When using Blink Dagger or Shadow Blade, cast Overpower before initiating so that its cast time doesn't prevent you from attacking and to let its cooldown run lower for an additional use.
 * While used primarily for its slow, Earthshock has an extremely low cooldown and mana cost and, assuming you don't need to save mana for other abilities or items, can be spammed for additional area of effect damage; however, be wary of its long cast animation, as it may allow fleeing enemies to retreat out of melee range.
 * Given that because of Fury Swipes Ursa Warrior's damage consistently increases, on equal terms there are next to no heroes who can actually battle him alone. Consider making attack speed, and durability increasing items as due to his passive and ultimate Ursa does not really need damage items.
 * With proper management of tangos and salves, Ursa and Wraith King can kill Roshan at level 1. Beware, however that most veteran players are aware of this and it is a risky gamble that, if successful, will give your team a huge early game advantage. This tactic can also be achieved with Ursa and Io, as well as many other heroes such as Anti-Mage, Lich, and Treant Protector.
