|Guard tower in the upper or lower battlefield.|
The Upper and Lower Battlements are defensive structures produced under the "Guard Tower" tab in the Graveyard. Although Battlements are technically buildings, they function like units on the battlefield. Battlements regenerate after each battle.
Early game: In early game situations where most game players don't have access to high-level heroes or units higher than Tier 6, level 4-6 battlements are very effective at preventing farming raids.
Late game: Conversely in late game situations where most active players have access to level 100 Heroes with Tier 10 units, level 10 battlements won't kill a single unit, and moreover, the Tier 10 stacks will kill the battlements in one hit. However, high level battlements do have one key benefit: they prevent against Scroll Bombing by making it very difficult to use scrolls to destroy battlements.
