Mirkwood Archers (Sindarin: Pengryn Taur-nu-Fuin) are the late-game alternative to the Lórien Borderguard Archers for the Lothlórien faction. They can be recruited from the Mirkwood Outpost once you have built a Troopchamber on one of the build plots.
Ambush of the Woodelves - The woodelves ambush their enemies. Mirkwood Warriors knock back enemies with their attacks for 15 seconds. Can only be activated when the battalion is in stealth.
The Mirkwood Archers have access to the following upgrades:
Banner Carrier - This upgrade can only be given to a level 1 battalion and will promote it to level 2. At level 2 the battalion can regenerate units when out of combat. Cost: 200
Silverthorn Arrows - This upgrade adds a bonus MAGIC damage to the battalion, causing it to deal greatly increased damage to everything and even more to buildings. Cost: 700
Longbows - After being purchased the Longbow upgrade increases the range and vision field of the equipped battalion by 20%. Cost: 200
All these upgrades must be researched at Forge before applying on battalion.
Mirkwood Archers are an upgraded version of Lórien Borderguard Archers. They can be perfectly used to protect your Lórien castle (when playing castle maps), because their skill Disruptive Shots proves useful to slow enemies as they fire from castle hubs, so in late game Lórien Borderguard Archers can be replaced by them. They can also just be used for protecting Mirkwood Outpost.
