Part 21

Isengard Mission: Complete all bonus objectives to make the mission easier. Build 1 Uruk pit and 15 lumber camps. Explore the map with Saruman to level him up; his fireball attack (unlocked at level 2) is crucial for damaging Ents and buildings. Merge existing Uruk fire crossbows with Uruk-Hai for a meat shield against Ents. Utilize orc laborers for faster Ent chopping. Build at least 100 Uruk-Hai after dealing with Ents and elves. Prepare your fortress against Rohan attacks by bottlenecking the main gate with Uruk-Hai in defensive formation, followed by Uruk crossbows. Use fire crossbows and Uruk battalions to flank Rohans. Continuously queue more Uruk-Hai if casualties are high, as lumber camps provide sufficient funds. Use Saruman's spells on large enemy groups.

Fangorn Mission: Start with surviving Uruk-Hai from the previous mission. Prepare for an elven attack. Move Saruman to a campsite to the right of your starting point with Uruk escorts; be ready for an ambush by elves upon unpacking. Build one pit, one armory, and fill remaining slots with resource buildings (slaughterhouse and furnaces). Get the banner carrier upgrade from the armory for orc horde regeneration. Attack the elvish base with a decent army, including fire crossbows, to counter two Ents. Level up Saruman by participating in the attack. Place Uruk-Hai on defensive formation before battles. After defeating the elves, build an outpost near their base with more resource buildings. Produce at least 4 hordes of merged crossbow Uruk-Hai with fire for hunting Ents. Deal with elven ambushes across the river. Approach the Entmoot in the East with your main army waiting outside Ent range, and have Saruman approach the Ents alone.
