Orb of Vulnerability
	Class:	relic
	Slot:	miscellaneous
	Cost:	25000
Effect: During combat, this orb negates the natural magic resistance of all creatures on the battlefield.

You meet an old Wizard friend of yours traveling in the opposite direction. He presents you with a gift: An orb that allows nearby magic resistant creatures to be harmed by magic.

Orb of Vulnerability is a relic class artifact equipped in the miscellaneous slot. While equipped, the orb negates natural Magic Resistance of all creatures. While not mentioned in the description, the orb also negates the Resistance secondary skill and any resistance granted by the Garniture of Interference and/or its components. Does not negate Golem's spell damage resistance.

Relic class artifacts cannot be purchased from Artifact Merchants.

Only the Orb of Vulnerability can negate the Black Dragon's resistance.

How does the Orb of Vulnerability work

First, let’s start with the fact that the Orb doesn’t work the same way for its owner and opponent: the owner can cast spells that could not be casted previously on both his own and enemy troops. The enemy also gets the opportunity to cast spells that could not be casted previously but only on the troops of the owner of the Orb. Example:

• Red hero has Gold Dragons, Efreet Sultans and the Orb of Vulnerability.
• Blue hero has Black Dragons, Efreet Sultans, but doesn't have the Orb of Vulnerability.
• Red hero casts Armageddon which deals damage to everyone on the battlefield.
• Blue hero casts Armageddon which deals damage only to Red troops (i.e. Armageddon resistance of Blue's Efreet Sultans and Black Dragons is not negated).
• Red hero can resurrect Gold Dragons.
• Blue hero cannot resurrect Black Dragons.

From the description of this artifact, it might seem that if it is available, you can cast any spells on any creatures. But this is not true. Creatures partially retain immunity to certain spells or their groups. The following table shows what happens when using this artifact. In the second column, for clarity, indicated all spells to which creatures are immune, and in the third column the spells, to which this or that creature remained immune, even with the Orb. A dash in this column means that the artifact really removed all the immunity of this creature and allows you to cast all spells on it. The table, of course, did not take into account the obvious things - the inability to cast the Death Ripple and Resurrection spells on the undead, and the inability to cast the Animate Dead and Destroy Undead spells on the living.

User commentary

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. However, the Orb of Vulnerability can be a double-edged sword if the enemy has a strong damage spell, and cannot destroy infamous Dragogeddon tactics unless you have Armageddon's Blade.
