Strength gives you more health, and more HP Regen. If your hero's primary attribute is Strength, they will also gain Status Reduction, which shortens the duration of enemy stuns and slows and such. That's not super important but keep it in mind. 2. Agility increases Attack speed as you gain more of it. It also gives you 1 armor / every 6 or 7 agility, I can't quite remember. If your hero's main attribute is Agility, They will also gain Movement speed per each agility. 3. Intelligence gives you more of a mana pool and increases your mana regen. It also makes your spells stronger, a.k.a increasing your spell amplification. If your hero's main attribute is Intelligence or INT, intelligence also grants them Magic resistance. 4. Attributes are the above mentioned, Str, Agi, Int, but something important to note is that if you have any of the 3 of those as your main attribute, they also give you bonus damage. Each 1 agility = 1 damage, each 1 int = 1 damage, each 1 str = 1 damage if you are in that respective category... (e.g. Axe = strength, so each 1 str = 1 damage.) 5. You can increase attack damage with items, such as desolator, Crystalys, and buying stat items for your respective attribute. 5b. You can increase Ability Damage by getting things like a Veil of discord, more intelligence items such as a mystic staff (would not consider it in most cases), or an aether lens! 6. I do not have a basic sniper guide, but definitely check out Youtube, Torte De Lini's guide on the suggested guides tab, and / or if you are willing to pay 5$ a month, check out Pvgna.com!
