The idea i had in mind would require a rewriten alchemy i suppose.
Anyway, i would like 'dynamicalchemy' added to the existing 'static alchemy'. (where 'static alchemy' is reproducable at some success rate, and 'dynamic alchemy' is more or less a quantum mechanic process)
Let me elaborate 'dynamic alchemy':
it would require
- high lvl alchemy skill
- rare ingredients like rare rings/amulets, rare food, ...- items you only can find 'somewhere in the world' or high lvl alchemy products, so you _have_ to risk your life - or at least: someones life

- an enchanted cauldron (+2 at least, higher is better results)
it wont have plain formulae
- there is a base recipe, more or less like 'static alchemy' with more or less equall items
- to create really powerfull stuff, you need to add 'things'.
- the recipe would not just require high lvl alchemy skill, it should also have a random change of 'failure'
- failures are defined as: not giving the intented result
- the 'not intened result' is one of (for example) the following: [other 'dynamic alchemy' artifacts; artifacts; other items; uncontrolled mana; evil masters; other monsters; nothing happened; some ingredients disappeared; all ingredients vanished; random teleportations; ...]
- items thus created are marked as start_equipment
- success rates (at a lvl 'static alchemy' gives 100% success rate): 'intented result' around 40%; other 'dymanic alchemy' items around 30% other results: 30%
If you know the base formula, you're ready to try and try again with different additions. (as listed above)
Just the base formula wont give you really powerfull stuff, though if you add some ingredients, you can find surprising results

what ingredients to add?
A good guess would be a fragment of chaos to add chaos resistance (where resistance is defined as: +90 for attack stuff; +100 for other stuff)
celestial fire to add fire resistance,
a frost hammer to add frost resistance,
troll stuff gives regeneration
then, two troll stuffs might give more regeneration, two fragments of chaos might give better resistance - who knows, even 100?
maybe addition of stats could be possible too. using stat potions to do this is a bad idea (too easy to get)
ok, thats enough for now - if not too much
