Elements

Elements cover all the attack and defense types, along with their status effects.

Fire
Found in: Pixies, Swords, Axes

Strong against: Trolls, Cupcakes, Mascots

Weak against: Kobolds

Pixies casting their spell may leave flames on hexes they strike.

Ice
Found in: Mortars, Medium Bows, Small Bows, Swords

Ice attacks have a change to freeze the opponent, another type of incapacitate, although it halves all damage to the victim.

Lightning
Found in: swords, bows, mortars, Electrobots

Strong against: Mascots, Pixies

Weak against: Gnomes, Wraiths, Gorgons

Electric attacks may shock the target, resulting in a different kind of incapacitate, similar to the stun of axes or thrown items.

Poison
Found in: Mushrooms, Swords

Strong against: Cupcakes, Mascots

Weak against: Electrobots, Zombies

Poison will deal damage at the end of an afflicted unit's turn, applying further bonus damage if the unit is weak to it. Mushrooms may leave gas clouds on empty hexes they fart around. Applying more poison to a poisoned unit will reset its duration.

Acid
Found in: Gorgons, Swords, Bows, Maces

Strong against: Electrobots, units with no defense

Weak against: Gorgons, Wraiths, Octoclopes, Gorgon Snakes

Explosive
Found in: Swords, Heavy Mallets, Medium Bows, Small Bows, Mortars, Axes

Strong against: None, merely add normal damage to surrounding units

Explosive weapons usually deal more base damage and have a chance to add an explosion to their target, which hurts nearby units and adds more damage to the target.
