"Magic & Mayhem: The Art of Magic"

burning

not everything burns
The terrain does not burn. Most artefacts (trees, bushes, ground cover) do burn.
dryads are particulary susceptible to fire.
skeletons don't burn at all.

extinguishing fires
You can't put out fies. If your troops are on fire, you will have to wait for them to stop burning. Changing your skin to stone (gorgon stare) or metal (iron skin) will not help, nor will walking through water. Healing spells (heal) and (totem of life) will similarly have no effect.

chaos creatures

The following creatures are chaos alignment

zombie,
skeleton,
dwarf boar rider,
harpy,
wraith,
vampire,
demon

dragon
They can be seriously harmed using bury or judgement.

collectors

A collecting creature will, when idle, go out of it's way to pick up useful objects on the ground such as food and enchanted items. These creatures are:

harpy

goblin

elf

centaur
Obviously this makes these creatures very useful in games where items have been set to be regenerate quickly.

eaters

The following creatures CANNOT eat food to replenish energy

skeleton (no 'body' to digest)

wraith (essentially a skeleton too)
Every other creature, and wizards, are able to eat food and restore health by doing so.

elementals

The following spells are considered elementals (a spell which calls upon the power of an element, and then disperses)

fire elemental

wind elemental
There is no water elemental, or earth elemental to complete the set. Both these elements are represented as artifacts which remain on the terrain, making them totems.

enchantment spells

Affected spell enchantments are weapons such as

All enchantment spells can be instantly removed with the area effect disenchant

flying creatures

A flying creature can cover different paths to other creatures, flying over chasms, and over ledges, and in a quicker/shorter path, making them very useful. These creatures are:

harpy

dragon

eagle

griffin

However they can be seriously harmed using gorgon stare which causes them to turn to stone and fall to their deaths.

hovering creatures

The only difference between hovering creatures and normal foot soldiers is that hovering creatures can cross water. These creatures are:

wraith

vampire (in bat form)

faerie
However unlike flyers, hovers turned to stone using gorgon stare do not fall to their deaths (they are not considered high enough) and thus are somewhat safer.

law creatures

The following creatures are chaos alignment

faerie,

elf,

centaur,

knight,

griffin,

storm giant,
Lawful creatures can be healed by judgement.

pickupers - creatures who pickup

The following creatures CANNOT pick up items ( food or enchanted items) if tasked to do so:

dragon (feet/wings)

eagle (wings)

faerie (too small)

giant spider (feet)

griffin (feet/wings)

wolf (feet)
Every other creature, and wizards, are able to pick up food and enchanted items from the landscape. However only wizards can pick up mana sprites.
