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
* It's possible(although unlikely) that if the Ursa isn't high enough in level(say under 11), it is possible for Roshan to repetitively stun Ursa, resulting in Ursa losing the fight.
 * Fully leveled Fury Swipes and Vladmir's Offering (or another powerful lifesteal) allows Ursa Warrior to solo Roshan relatively early (from level 7 onward without other itemisation). 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.

Trivia

 * Ulfsaar's alternate name was Fuzzy Wuzzy.
 * In Latin, the word "ursa" means bear.
 * In DotA, Ursa's Ultimate would do damage at the start of his attack animation.
