Here's some drakes I modded in with the help of this forum.  Intended for low-metal embarks, or just a leg up until the metal can be smelted.  Anyone wants to use them go ahead.

They're reptile like creatures that resemble small dragons, roughly the size of a dwarf.  Their scales can be harvested to make armor out of, being slightly harder than copper.  Though it can't be made into weapons.  It protects the drakes somewhat.  They're harvested with the shearing skill and grows back faster than wool.  It's worked much like shell is by a bonecarver.

Their bones are heavy, a little lighter than silver, and can be made into picks, though almost worthless as an edged weapon, and maces.

The three varieties are the drake, the whiptail, and the clubtail.  The drake being the average version.

The whiptails are quite smaller than the drakes, though much more agile.  Their long tail is used by them as their namesake suggests. (Note that in this version whips are blunt weapons).  They can only be trained as hunters.

The clubtails are larger than drakes and much hardier.  They have a club-like spiked knob of bone at the end of their tail, which they use as a weapon.

They're all domestic pets, though they can also show up wild in a mountain biome.

I've tested them myself and they give no errors in the errorlog.  Though I'd appreciate any help with making sure they're working as intended.

Known issues:  Custom reactions use an entire stack at once to make a single result, while the standard reactions use just a single part of a stack.  The armor is under the shell option in the craftdwarf's workshop, while the custom reactions are at the end.  The weapons and shield are only as a custom reaction, while the armor is both.  So you can make the mail armor using a single scale, but sometimes your civilization doesn't have access to a particular style.  In which case you have to use the custom reaction.

Boots and gloves don't have handedness when made as a custom reaction.  Boots can ignore handedness, while gloves must have it.  Which means that there's no custom reaction for gloves since they'd be worthless.  Fortunately the shell gauntlets seem to always show up.  You also end up with two boots at once with either the custom reaction or the standard shell reaction.

All armor is considered metal armor by the game.  It is treated like chain armor, and you can only wear one of each.  Except the standard shell gloves and helms are plate.

The whiptails and clubtails may be a bit too tough.  Let me know if this seems the case.


Just copy/paste these into the end of the appropriate files.  Except the entity one, which must go into the dwarf portion of the file.  And the first one, creature_drake.txt, which you just need to make a new file with that name of.

creature_drake.txt  Remember to make a new file named this, then copy this into it

these go into the appropriate item_*.txt file, depending on the item

reaction_other.txt

entity_default.txt  Remember to put these within the dwarf portion.

tissue_template_default.txt

material_template_default.txt

body_default.txt

Let me know if I missed anything.  And I plan on making dragons similar to this later, though not domestic pets.

EDIT1  Corrected a typo in the tissue_template part, added a new creature to the creature_drake part, and added a new material to the material_template part.

Iridescent wyrm, a very small drake.  Hunts vermin and has beautiful scales used to decorate like pearls.

Iridescent scales have a large variation in stack size, an entire stack is used at once, and small stacks might not actually work (2 size).  Still a good and cheap method of increasing furniture value.

EDIT2  Three new drakes and minor changes to creature_drake.  Changes mostly being tags like [LARGE_PREDATOR], and none of the new creatures are domestic.

Wyvern, a limbless flying drake with a poisonous stinger.  Regular bones and scales can't be sheared.

Rager, a small drake that hunts the deserts and tropical savannahs in packs.  Fortunentally rarely encountered.  Scales can't be sheared.

Darter, an amphibious drake that inhabits lakes and rivers.

EDIT3  Corrections to creature_drake and tissue_template_default.  And adding dragons down below.

EDIT4  Modifications to creature_drake, increasing the chance of one showing up.  Added mail gloves to the item list and to entity_default, which can't be made with a custom reaction but were added so that there would be a glove in the shell list just in case your civilization can't make gauntlets.

EDIT5  Modifications to creature_drake.
