Part 12

Fangorn (Eomer): Secure Ent support from the top of your starting point. Use the Ents to guard the top path while you secure the bottom. Attack the enemy camp in the top left, ideally after leveling up units and Eomer.

Eastfold (Eomer, Gandalf): Group Eomer with Rohan units. Assign Gandalf to a hotkey. Level Gandalf to level 5 to enable him to mount Shadowfax and use the powerful Light of Istari spell, capable of defeating a Nazgûl when Gandalf is maxed out. After Gandalf is mounted, clear the map of enemies.

Helm's Deep (Fellowship minus Hobbits, Rohan Heroes): Build an archery range on the left and produce archers rapidly. Construct an armory and acquire all upgrades, prioritizing the banner carrier upgrade. Position archers along the wall, including Legolas, to grant experience. Group Theoden and Eowyn with Rohan units, send them out to save refugees, and retrieve money at the front gates. Have them defend the main gate once Elven reinforcements arrive. Position Elves and Yeomen archers on the left wall. Heroes should support archers and have hotkeys for micromanagement against berserkers and siege ladders. Retrain lost archers. Be cautious of mines on the left wall during the third wave; destroy orcs planting mines before they reach the wall. Gimli can leap from the wall to clear the main gate area when attacked. Use cavalry to clear survivors, then retreat inside and have peasants repair the gate. If the left wall breaks, retreat to the inner wall, reposition archers, and have Rohan units and heroes cover (press the cover button to crouch behind walls or objects) the retreat. Allow Uruk-hai to attack buildings before retreating units. After reinforcements arrive, regroup, clear remaining enemies, and destroy enemy encampments.

Isengard (Merry, Pippin and Treebeard): Group Merry and Pippin. Hotkey Treebeard. Create groups of 5 Ents, with some on ranged attacks and others on melee to protect them. Destroy the cave troll's lair at the top for extra resources. Use hobbits' throwing rock abilities to quickly eliminate crossbow orcs, ensuring their health bars are monitored and they retreat to Treebeard if threatened. Before destroying walls, destroy buildings within Ent rock-throwing range, starting from the top. Prioritize destroying the armory to reduce fire crossbow effectiveness. Build more Ents to replace losses and reinforce your main group. Summon Rohan reinforcements if available to trample armored fire crossbows while Ents handle pikes. This mission can be completed in under 20 minutes.
