This is a silly little mod that adds a new reward to the quest Seeking your Roots. If you've managed to find & hand in 100 Nirnroots, you will acquire the perk "Sinderion's Serendipity" which gives a chance to create two potions instead of one when performing alchemy.
The chance to get double potions is stored in the Global variable lSSDoublePotionChance, if you wanna tinker with it in xEdit.
The custom icon will not appear unless you are using Custom Spell Icons.
If you are using Custom Spell Icons, or the updated variant that works with OBME, add this to one of the CSI inis to get a custom icon for the ability:
set CSIQuest.iconPath to sv_Construct "Laula\SSNirnrootIcon.dds"
set CSIQuest.spellRef to (GetFormFromMod "lSinderion's Serendipity.esp" 000807)
SetStage CSIQuest 10
To use this with Alchemy Advanced, the addon Alchemy Advanced Adjustments is needed.
2020-05-20: Updated to show how many bonus points were made after closing the alchemy window, and to automatically apply the new icon when CSI is detected
2020-05-30: Hopefully this time the ability icon will stick after restart.
