Talk:Orb of Vulnerability
Orb of Vulnerability can be a huge against enemy creatures with strong magical resistance, but it can also be used to strip allied troops immunities. For example, with the Orb Black Dragons can be resurrected. Additionally, using Armageddon's Blade and Orb of Vulnerability at the same time makes all enemy troops vulnerable to the Armageddon spell, but still leaves allied troops immune to it. That makes a perfect combination for the Dragogeddon tactic.
