In this post i share with some information about main mod mechanics - Essence Collecting.

My main idea on race-specific  properties/effects of essences. Essences collected from being (human, elf, beastfolk race, aimal, creature), contains its race effects. As example, for Nords - cold resist, for Argonian - water breathing, horse - increasing stamina. 

For playable/custom races we have possibility to collect gender-specific essence - sperm or squirt. So if you play male character, you get after sex your sperm and squirt  of your female partner (as example).  For animal races you get it's sperm - wolf, bear, horse, troll and other - because most creatures a males. Yes, we have some male-on-female-creature animations, but it uncommon variant.

Playable race essences (human, elfs, beastfolk races) have some grades of quality

• Raw Essence - fresh collected essence, not so effective.
• Distilled Essence - you get it through distiallation process on alchemy table. 
• Concetrated Essence - you get it after concetration with special sellable ingredient (catalyst)
• Racial Essence - high-level essence, required for some potions with race effects.

Essence collecting process full-controlled by my mod, use Sexlab hook system, and no need other mods to work. Essence collecting requires bottles in inventory and special collector skill, which you get due to quest line. Skill level affects on count of received essences, their quality.

For collecting purposes in shop basement i place some animals in cells.  New creatures will be accessible by quest line. Also, i provide "Conjuring Book" for some unusual creatures - Seekers, Atronachs, Dremora, Ghost and other non-animal creatures. This also can be accessible as quest reward.

The main difference between these essences and ordinary ingredients is the absence of a magical effect. Technicaly, it realized by consumables/ingestibles (ALCH-form) with blank effect. You can't use standard alchemy table for its combining, you can teach effect by consumming. Mixing will be carried out strictly according to specified recipes, the availability of which will depend on the skill level.

Other ingredients

Also i add some other ingredients, from other games (Oblivion, Morrowind, TES Online). They will work as regular, standard effects based on TES Wiki/Lore Books description. Some of its will be collectible/plantable, some sellable by vendors (i update leveled lists of vendors).

For some of its i plan use Special Flora ingredients, or public models of some IRL herbs/plants.

May be in future i add some harvesting functions - tree sap, blood, organs.

Ingredients effect book

I provide custom mechanic for teaching properties/effects of all vanilla ingredients - Book of Alchemist's Knowledges. This special book will be placed in main laboratory, and with it activator you can randomly teach new effects of vanilla ingredients - no more consuming. Access to this feature, of course will be granted due to quest line, and will be limited and time (once a day).
