kn1tt3r: My guess is that it's strictly about the category, i.e. those Giant and Tiny creatures are excluded from certain mulitplyers (the same goes for the flying insects), but I'm still not sure, and it wouldn't really make much sense.

kn1tt3r: The Beastslayer Axe scores double damage against Beasts. The Light Sword and the Mystery Ray does double damage against Androids.

Does this category refer strictly to the monster info from the game or also, well... common sense?

For example:
Scorchers are in the "Beast" category, but Furor is not (he is categorized as "Giant"). Is Furor still a Beast with respect to Beastslayer damage?
Also bigger Crabs (Hardshell Crabs, Crusher Crabs, etc.) are "Beasts", but the smaller ones (common Crabs, Venom Crabs, Softshell Crabs...) are "Tiny".

The same thing goes for Golems - all of belong to the category "Android" (i.e. 2x damage with Light Sword), but Pee Wee is "Giant" again.

For insects it's even more obscure (if there were an Insect damage multiplying item): Here you have the same thing as for Beasts (common Roaches are "Tiny", but Gregor or Dank Beetles are "Beasts"), but there are also Wasps and Mosquitos, which are obviously insects, but belong to the category "Flyer".

My guess is that it's strictly about the category, i.e. those Giant and Tiny creatures are excluded from certain mulitplyers (the same goes for the flying insects), but I'm still not sure, and it wouldn't really make much sense.

ussnorway: The axe works on any Beast (race) so Picus or Diamond Unicorn are in trouble but Ants arn't...
