Strategic Traps - Tier 1 - Tier 2 - Tier 3 - Tier 4
Tier 4 strategic traps are the most powerful, but expensive Strategic Traps. Just like all Strategic Traps, Tier 4's also require their Standard Troop counterpart, as well as the Tier 3 version to already be researched, as well as a Lv. 21 Academy and the max level of Strategic Trap Defence. Unlocking Ballista Towers requires Defense Towers and Trebuchets to be researched, Smoke Bombs require Poison Swamps and Greek Fire to be researched, and War Barricades require Pendulums and Spiked Barricades to be unlocked.
- NOTE: The trap type (eg. Ranged) refers to what the trap is strong against.
