Current sniper agha is just a bad joke so I'll repost my thread from old Playdota. Unfortunately I can't find my thread from PD archives so I'll keep it short here without all the indepth analysis. Upgrades Take Aim Taking hostile action will not reveal your position in fog of war In other words it makes so your opponents can't see where you are shooting as long as you are holding aghanim and outside their vision range. Very convenient during night time, has obvious synergy with Shrapnel vision etc. Enemies can still see your projectiles, albeit only when those projectiles reach their vision range. Sniper's basic attacks are fairly hard to see in fights without any attack modifiers.
