Ch'r'ai Tska'an and her group of gith will ambush the party as they are approaching the Road To Baldur's Gate Waypoint. Carrying the Qua'nith Psionic Detector, whether gifted by Voss or looted off his body, allows the player to more easily spot their ambush and surprise the raiding party.
Tska'an and her squad will block the player from proceeding to Baldur's Gate and Act Three. Tska'an begins the battle standing on an archway flanked by two Githyanki Raiders who will often use Trip Attack and Arrow of Many Targets. Below her are two Githyanki Warriors armed with Supreme Githyanki Parry.
All members of the gith ambush carry weapons imbued with Light, to protect them from the weaker areas of the Shadow Curse on the border of Reithwin.
An effective way to begin the fight is using spells like Enhance Leap, Misty Step, or Dimension Door to get the entire party onto the top of the archway and begin focusing attacks on the raiders. The warriors below will be forced to waste a turn or two taking the long way around or using Githyanki Psionics to follow with a jump.
While Tska'an herself is immune to the Shadow curse, her allies can all be affected by it. Retreating deeper into the town of Reithwin will cause the darker shadows to extinguish the Light spell on their weapons, causing them to take damage from the curse every turn. However, if they die to the curse in this way then they'll be revived with half health as Shadow-Cursed Undead.
