Dazzle

Dazzle is a ranged hero that uses his skills to mainly support his allies in battle. While frail, he's capable of keeping his allies and himself from dying, causing his foes to waste time in a fruitless endeavor. Due to this, Dazzle is typically an oft sought target, making the player's job more difficult, but rewarding.

Dazzle is recommended for new to intermediate players. Despite having no passives, his skills are fairly simple to use, require no positioning, and the timing is not as crucial as other heroes. However, newer players will may have trouble remembering to use each of them, since they all have quite low cooldowns.

Tips

 * As of the current update, almost every single skill build recommends you leave Poison Touch at Level 3; the 4th level of damage makes neglible difference, and the stat can be put to better use for almost anything.
 * Don't forget that Shadow Wave deals damage around your healed allies as well, roughly a Melee hero swing and a tiny bit more; a bit similar to Omniknight's Purification but with much less raw healing.
 * Each level of upgrade for Shallow Grave makes it cost less mana; if you're having mana problems, consider upgrading it sooner rather than later.
 * Your first skill can be any of the three depending on the situation; Poison Touch if you're hunting for first blood (with teammates, by yourself or with a single lane partner is probably not enough and can be risky in the event of a reversal), Shallow Grave if the enemy has not been spotted in their lanes and you suspect a possible gank incoming, and Shadow Wave if you're fighting an aggressive meele gank with an ally.
 * Don't forget that the range of Shallow Grave increases with each level; it starts out less than your normal attack, but at level 4 goes to twice that length. You don't want to have an ally die just because you had to run in closer.
 * Using Shallow Grave is the most tricky skill of all, and one of the chief reasons why Dazzle is complicated; you're giving either yourself or an allied Hero five seconds where they cannot die. For newer players, it is often better to use it earlier than never; 2 seconds of life for an ally is better than none. More experienced players can gauge the situation of battles better, and can determine if burst damage has already been applied, amount and length of incoming stuns, and if they're directed at Dazzle, etc. In the early game laning phase, you can aggressively attempt a kill and then use Grave on yourself once you're near death; however, this can easily backfire due to burst damage and stun, preventing you from even using the spell. In the mid game, your priority to grave are heroes with burst/ultimate's that haven't been used yet, such as a Sand King Epicenter, a Tidehunter's Ravage, or an Enigma's Black Hole. Typically, the use of such ultimates would change the tide of battle in your favour, although this would only apply if those types of heroes are caught out of position, or are about to die before they can use it. Preventing a hard carry from dying and losing their gold is also important, but not if it means losing the teamfight and being able to push. With the late game especially, keeping your hard carry alive now becomes crucial on the priority list. You may have to choose allies to be sacrificed to save another, and that choice will ultimately rest upon you. For example, choosing between keeping Tidehunter alive after his Ravage has been used is a poor decision versus keeping a fellow Lycan from dying.

Trivia

 * Dazzle's Ultimate used to be Shallow Grave, which had a totally different effect on the player who was buffed by it, reducing the revival time if the Grave'd player died under it's effect, while Weave was a Normal Single Target skill until a Dota Update where this was changed to the current set-up.
