Weaken Resistance to
EDIT: This is a placeholder direct copy of the Weakness to Attacktype page, the original name of the now wikibot named "Weaken Resistance To" unit ability.
All undead units, and only undead units, have a weakness to HOLY. This weakness cause a -50% Damage Resistance penalty to the combined (averaged) resistance of undead units against any attack with a HOLY type. Example: ignoring HOLY resistance boosts, wraiths have a (0 - 50 = -50)% resist against pure HOLY attacks, but a ((0 + 40)/2 - 50 = -30)% resist against HOLY RANGED attacks.
In addition, a number of units are vulnerable to elemental attacks, specifically fire, cold, and lightning. Any attack including one of these types will do double damage to any unit with the matching weakness.
- Only the Earth Elemental has a weakness to LIGHTNING.
A number of fire-associated Eradication units have a weakness to COLD:
The most common weakness is that of FIRE. All TREEFOLK and one unit from each other color is included in this group:
