MUTAGENOLOGY UPDATE FOR 3. 4 EE Authors: niktesla, EstevaoCM, Kamilius Version: 3/27/2014

Viking 99 is nice enough to have allowed me to upload a merged file of both our mods in the downloads section. Install instructions are the same.

Hi all. It's my first mod for ANY game. I liked the mutagenology so much I had to get it working. I figured out that the problem was with the en0.w2strings file not allowing shops to receive the new items. I needed to edit this string file with the name of the new schematic and it worked! This mod is also compatible with vikings item rebalance mod, which I highly suggest. It works with mine so it should work with yours. However it is not compatible with any other mod that edits the def_item_schematics.xml, def_item_mutagens.xml or def_shops.xml files or en0.w2strings file. ============================================================================================================ - DESCRIPTION -

Simple mod that allows you to combine lesser mutagens into more powerful ones (e.g. three Minor Mutagens of Power gives one Mutagen of Power). Combining also requires some additional non-mutagen ingredients.

Combining mutagens is possible only by crafting. You need to get a proper schematic first. All schematics were added to Mysterious Merchant Shop and other merchants in-game. Then just ask any craftsman in game to combine mutagens for you.

You CAN'T create Minor Mutagens nor Mutagen of Concentration

- INSTALLING -

Unpack and put "items" folder into your "Witcher 2/CookedPC" directory. Also put en0.w2strings in the main cookedpc folder. Make sure to back up everything first.

- UNINSTALLING -

Simply delete "items" folder or def_item_schematics.xml, def_item_mutagens.xml and def_shops.xml files in it (in case you have other mods that install do this folder).

  • Tooltips in schematics descriptions
  • Fixing journal entries
  • Maybe other languages versions?

- CREDITS -

Originally created by Kamilius, last version v0. 3a BETA.

===========================================================================================================

- CHANGELOG -

2011/10/01: Applied Kamilius' modifications to the XML files extracted from patch 2. 0 of the game.

============================================================================================================

- IMPORTANT NOTES -

This mod will NOT work with other mods that change def_item_schematics.xml, def_item_mutagens.xml or def_shops.xml files.
