Recruit the brothers of Haldir - Rúmil and Orophin. They are the scouts of Lothlórien. They are both recruited from the citadel under one icon but are two separate heroes (unlike Elrohir and Elladan). They share experience once they are on the battlefield and have the same abilities. Rúmil is equipped with a bow and Orophin wields a sword. You can still use their abilities when they are both selected.
Level 1: Concealed Strike - Rúmil/Orophin uses his elven cloak to hide from his enemies, becoming invisible for 10 seconds. During this time, he can still move around and temporarily reveal himself to attack.
They can receive only one upgrade:
Gifts of Lorien - Galadriel hands gifts from Lothlorien to a hero. The gift can increase the stat of the heroes and/or grants it upgraded abilities. Rúmil and Orophin are gifted mighty elven armor that highly enhances their defense but lowers their speed. When the ability is cast on either the brothers both will get the armor.
Rúmil and Orophin are scout heroes, which means combat is not their strongest area. However, they can be better equipped for combat once they have the Gifts of Lorien upgrade and can make use of their level 7 ability, granting them +50% damage and knock-back for a short time. Their other abilities allow them to become invisible and move much faster, which can be used to track Gollum and get the Ring or to capture settlements. If only one of them dies, you will have to wait until the other dies as well to recruit them both again from citadel.
