Did you even read what I posted? As I quoted, "As written in the Ch&CL, "armor type 3, 4, 11 and 12 are animal armors, natural body coverings with no armor equivalents. One cannot achieve such an AT without acquiring some enchanted and specially designed armor."" So, no, AT-12 isn't any kind of armor at all. It does NOT have any armor equivalent. As such, you shouldn't be able to "purchase them from the larger cities with good traders" because they should be very very rare, since "enchanted and specially designed". Now, if every time you roll for magical items, get armors, and get an AT12, and your GM allows so (or makes them common items), he shouldn't "rejoice" when someone chooses an AT other than AT12...
Siiiigh. <--- look, I can condescending in a friendly forum just like you.
I read what was written in AL&CL (pp.10-11) and from what I have used first hand in Martial Arts.
"Rigid Leather base. Rigid leather armour and the rigid hide covering of creature <sp> like certain reptiles and of fantastic creatures such as dragons." pg. 11
Look ^ Rigid Leather armour AAAAAAAAND the rigid hide covering of a creature. Not "ONLY the rigid hide covering of a creature but ALSO the rigid hide."
"AT 11: Half hide plate. Rigid leather armour that covers the body completely, AND the hide of certain creatures that contain at least a few rigid plates." pg. 11
Note the use of the word "AND" in the sentence. This means that rigid leather exists and can be used, it doesn't have to be magical, just cured in a manner to make it harder.
"AT 12: Full hide plate. As half hide plate above except that the rigid leather or plates are harder and/or more plentiful." pg. 11
"AT 4: Heavy hide. The natural hide of certain classes of animals both normal and unusual." pg. 10
Wait.... I bet you're going to tell me that no one in the history of fighting made a protective cloak out of a bear or lion hide to cover themselves for just a little bit of protection. No nomadic hunters like say ummmm..... the Huns, used the pelts and hides of animals as protective cover? That would make it AT4 and since that's not possible, the Huns must have been magical to have come up with that armour type
Samurai armour was boiled leather, rigid leather armour. I've worn it for Kendo (rigid leather pieces, NOT Samurai armour), I've practiced in it, and have sparred against it. I have seen it and touched it. It's not magical, mythical, or beyond the realm of possibility to have but it's extremely light and takes a beating. It's just leather armour that's been cured and molded to be tougher.
Hard leather/rigid leather/boiled leather, was used in feudal Japan CENTURIES AGO. Nothing magical or mystical about it.
You may not have heard of Samurai I take it. There's even a History Channel special on how 'ancient' armours were made.
Simply put, AT 11 and 12 are rigid leather which is leather that can be made stronger through non-magical means. There is nothing special about it that makes it so a level 1 PC can't have it. Leather is plentiful and easily worked and cured. AT4 is heavy hides. Nomads have worn heavy hides for protection before there was written word.
Oh wait, I've just realized: so, you're telling us that, because the information is missing from AL&CL, even though it's present in Ch&CL, you chose to ignore it, made easily available an AT type that isn't even supposed to be an actual armor, then wondered why everyone wants it and even rejoiced when someone does not want it?
Oh, and, just a note, it's just so rare than in both tables of the C&T p71, Type I and II armors, there's only ONE AT12, rolling a 91 on the Type II armor table and getting a dragonskin armor, and, even then, as clarified in the Type II armor descriptions p74, when you get this dragonskin armor, you have to roll another die and roll a 01-25. If using these tables, your PCs always get an AT12 and your GM always allows it, well... I don't know what to add.
Oh wait, I've just realized: so, you're telling us that, because the information is missing in Chl&CaL, even though it's present in AL&CL, you chose to ignore it. I bet you're going to choose to ignore the examples of the Huns and Samurai and their armour that I've given. I would have gladly discussed this with you in private messages, but since you chose the tone and lousy attitude and to make direct attacks at me here, I'll respond in kind here. You took a simple comment that was said in jest (GM's would rejoice when we would take different armour) and turned it into a giant personal attack. Pretty much all of our PC's had different armour by the time they hit Level 5 because they quested for and found better armour and of differing types.
I don't recall having any interaction with you other than this forum and not even in Private Messages, but for whatever reason, I've pissed you off. So I'll apologize now, publically, for having pissed you off.
