Seasoned Marksman

Seasoned Marksman was a generic Quest Talent that was purposed to provide steadily increasing Basic Attack damage from killing Minions and Heroes. As of March 2nd balance patch in 2021, all instances of original Seasoned Marksman have been modified or removed from the game altogether.

Seasoned Marksman has little effect early on but later in the game it can provide a sizeable boost to your dps if you stacked it well. Additionally it provides a strong but short-lived active component once stacked enough, and unlike similar Quests once the reward is obtained it can still stack beyond, allowing for an uncapped amount of damage. The damage is attached to the Hero's base damage so it's also multiplied by damage modifiers, like Follow Through. The bonus damage does, however, not scale on level up. It is not a very optimal Talent choice, if you're expecting to fight a lot out of lane.

Modified version

 * Illidan's level 1 "Unending Hatred", Minion kills grant 0.2 damage, Takedowns grant 1 damage, upon reaching 20 damage gain a bonus 20 damage. No active component.
 * Falstad'a level 1 "Frequent Flyer", Minion kills grant 0.2 damage, Takedowns grant 0.5 damage. Can be activated to gain 40% Attack Speed and Tailwind, but doesn't require completing the quest.
