In vanilla Oblivion the Quality of the apparatus are: (from Novice to Master) 10 - 25- 50 - 75 - 100

With this mod they are 20 - 25 -30 - 35 - 40, with the exception of the Alembic which is: 25 - 35 - 45 - 55- 65.

These numbers mean that in vanilla Oblivion an inexperienced alchemist who stumbles upon a set of Master apparatus can all of the sudden create potions and poisons of significant power, while a true master of alchemy who for some reason only has novice apparatus at his or her disposal, can only muster to create a mere ordinary potion or poison.

I feel that the skill of the alchemist should have a much higher impact on the strength of the potions and poisons, since a seasoned alchemist would know all the little tricks that you only learn from long nights of testing and studying the various plants, roots and whatnot.

I also have made these changes to shave off some of what I find as rather extreme values for home-brewed potions & poisons.

Let me illustrate by showing both the minimum and maximum values for potions and poisons and then you can be the judge.

I picked 10 effects to look at and then brewed potions & poisons with my alchemist character who first had Alchemy 5 and was using only a novice Mortar and Pestle (for the minimum values). Then I increased his Alchemy skill to 100 and gave him master Mortar and Pestle, Master Retort and Master Calcinator (for the maximum values) and repeated the process for both vanilla and modded apparatus.

Here are my results:

About the Alembic bug fix I mentioned at the start; the bugs are described here: http://www.uesp.net/wiki/Oblivion:Alchemy#Master_Equations.

The important part is these 2 oddities:

- Novice Alembic may increase the magnitude and duration of negative side effects by as much as 15%. (Note that they are supposed to decrease negative effects, not increase them).

- An Expert quality Alembic is sufficient to ensure that all negative side effects always have the magnitude and duration of 1; upgrading to a Master quality Alembic causes no further improvement.

With my changes to Alembics these 2 bugs cannot actualize.

Compatibility:

- Mods which changes the look of the alchemy apparatus are compatible as long as my mod loads after them and they are tagged with [Graphics] in Wrye Bash. If you don't use Wrye Bash you have to choose one over the other.

- Mods which edits the base cost of Magic Effects (such as OOO and magic overhauls) are compatible, however you will see slightly different min & max values in your game if you're using such mods, that's is all.
