Crafting

Crafting is not a simple skill with basic functionality, there are many different types of crafts out there that have wide ranging affects and implications. Several types of crafting are available by default, but this is by no means an exhaustive list. Specific rules are created for the basic examples, though any DM should be willing to design and work on a crafting skill for their players.

Alchemy

Alchemy is the term for any kind of crafting that involves chemicals. If in use with a more modern or contemporary understanding of things it can be called Chemistry as well. A crafting roll is used to make and determine the quality of what is created. Spell casters using this crafting can also turn their prepared spells into potions so long as they have a full alchemy kit. If a DC is failed the materials in the kit are wasted. If the DC is failed by more than 10 the substance affects the crafter. See the chart below for some suggested DCs and methods for this.

While grenadal potions that deal fire or acid damage only require a touch attack to deal damage, poisons that damage attributes require a fortitude save. Calculate the fortitude save of a poison as 10 + 1/2 HD + Intelligence modifier. The DCs for spells turned into potions will simply be the same as the DC for that spell. It takes a spell slot to turn a spell into a potion,

Field alchemy kits only have enough ingredients for 5 potions and without proper bushcraft or knowledge (nature) rolls, they cannot be filled out of a city. Field Alchemy kits costs 35 gp and weight 15 lbs; restock is 15gp. They contain small mixing vials, flasks, burners, and other useful tools. Fixed, or permanent, alchemy benches have enough to make 25 potions when fully stocked but weigh well over 100 lbs and are too unwieldy to carry around. If built properly they could fit on a cart. The general cost of a fixed alchemy kit is 500 gp, and restocking a fixed alchemy bench costs 150 gp.

Tinker

There are always people who like to fiddle and mess with things to do exactly what they want them to do. Often times this results in the invention of a small gadget that might make a mundane task simpler. Sometimes it allows the diving and simple modification of a more complex device. A lot of what can be done with craft-tinker is difficult to pin down and should be DCs set by the DM. Below will be a table with some examples how how this skill should be used. Most actions that repair or build something will require materials of some sort. You will also need a set of tinkering tools or you will not be able to perform any tinkering.

Result Desired	DC
Turn scraps into basic catapult	25
Disassemble simple mechanical device	15
Repair mechanical device	10 + 4 per 1d6 Repair
Minor change to function of a device	20
Major change to function of a device	35

This is by no means an exhaustive list and should be approached creatively by both the player and the DM.
