📋 About This Mod
THIS VERSION IS COMPATIBLE WITH THE NEXT-GEN UPDATE(4. 04) ONLY. FOR THE A VERSION OF THIS MOD COMPATIBLE WITH 1. 32 PLEASE CLICK HERE.
At some point in development, CDPR intended to have a fourth mutagen type, yellow, featured alongside blue, green, and red. Yellow mutagens were to link up with the yellow colored skills that in the vanilla game cannot link up with mutagens to provide an additional bonus. They were cut at some point during the development of the base game and CDPR did a fairly decent job and removing the feature from the game files. All the remained was an icon(which interestingly did receive the updated mutagen icon look in the 1. 08 patch), 3 lines of code, and some yellow colored "link-up" graphics buried deep in the panel_character.redswf file. However this was enough to be able to restore the feature.
This mod restores the lesser, normal, and greater yellow mutagens back into the game. CDPR left the bonus provided by the yellow mutagen as a bonus to attack power which is identical to the red mutagen. I'm pretty sure this was not intentional and was just a result of the feature being cut before it could be finished. To make yellow mutagens more interesting for actual gameplay, I have chosen to make them provide a stamina bonus.
As of version 3. 0 of this mod, yellow mutagens are dropped by the monsters that do not drop any mutagens at all in the vanilla game. The standard, greater, and lesser varieties can also be crafted.
The lesser, normal, and greater yellow mutagens function in the pretty much the same was as their red, green, and blue counterparts. They can be inserted into the mutagen slots in the character menu to obtain stamina bonuses of 5%/7%/10% for the lesser/normal/greater yellow mutagens respectively. They can link up with yellow skills in the same group to receive a +100% increase to their effect for each yellow skill in the group. Yellow mutagens placed in mutagen slots are also fully compatible with the Synergy ability which increases the bonuses of the mutagens currently in the slots. This is all similar in behavior to the vanilla red and blue mutations.
As of version 3. 0 of this mod, there is only a single version. In this version yellow mutagens are dropped by the following monsters. These monsters were chosen as they do not drop any colored mutagens in vanilla.
