The mod introduces many shamanic improvements to BG Series. After playing Siege of Dragonspear I had a feeling that shamans in BG1 and BG2 would use some nice additions. Keep in mind that the mod was created with BG2 in mind, so if you try to install the mod on BG1, you will only see the component with the new shamanic kit. In mod you can find:

=> the brand new shaman kit: Witchlight Shaman
=> Shaman's Stronghold along with optional change of shaman's class description (to erase "no stronghold" line)
=> Brand new NPC - Will, the undead witchlight shaman (may be joined on the Shaman's stronghold area, which is available for every CHARNAME)
=> A mini-quest to restore a certain area's power (first Stronghold quest which is available to every PC)
=> Optional new items for shamans and exclusive items for undead NPCs (like Will or Hexxat)
=> Optional new enemy types: driders and treants (you may now encounter just few of these)


Install like any other WeiDU mod, by unzipping the mod in your BG2EE game directory and running Setup-willowisp.exe on Windows or equivalent on other platforms.
You must have an EE version of the game updated to v2.0 or higher. The mod should be compatible with any other WeiDU mod.
This mod also can be installed with (after) the Enhanced Edition Trilogy (EET), before EET_End.
