For the dice rolling, just programmed my calculator to figure out how many rolls I failed during a 9 month creation process.
And then roll that number of spell fumbles, it is not?, yes, that is another solution, using statistic.
About alchemy rituals, I am not much agree with that, because with only 1 ritual you can cast most alchemy spells (enchant permanent and variable rituals), so they should be limited in any manner, if not, who wants to learn the spell lists?.
A pure alchemist is usually not used, the alchemist characters are mainly created by TPs, you can download the TP alchemist from the ICE Vault, and is great. But, again, who wants to make a TP if you can easily (and cheaper) do it by rituals?.
We have a good solution for 1 part of the process:
- We divide the alchemy process in 2 parts: 1 is the base item creation, 'work' and 'make' spells type. The other is the enchantment process, 'armor, general, charge, etc.' spell type.
- The 1st part requires 'laboratory' working, so you need the tools and the 8 hours time working.
- The 2nd part only requires casting the spells on item daily, until finished. If you don't cast the spells 1 day, you must substract it to the time you are enchanting the item, it can't be less than 0.
So, once you have the base item, you can go to adventures while enchant the item, only with less PPs per day as you need to cast the alchemy spells, and if you need all your PPs, you can save them, but adding time to alchemy process.
This is optimal for potioners, as they can create all base items (potions) as they can in resting time (pause between adventures), and easily carry and enchant them while adventuring, in a short time (x0.25 modifier to time).
This is a good excuse to learn the spells, as usually a group can't lost the time everyday for rituals.
- Maybe the other reason to learn the spells is that for rituals you need to search for many 'influences' to cast rituals, 1 per day, as usually you can only use 1 skill as influence per item type (attunement, runes, etc., but not both).
