Hi, I'm stuck in chapter 4 (BG2EE, iPad edition). I have Dace's hand but I can't seem to get the Kurtulmak crystal from the kobold avatar (I used an old stake from Bodhi's lair to kill Dace once and for all), maybe because I killed the shaman before he could summon him... now there's just a white cloud named "Altar" and I can't interact with it (it suffers AoE from fireballs and such, but I can't kill it). My most recent save apart from quicksaving (I know, I know...) it's from chapter 2. Do you know any way to get the crystal or to pass the giant head? Thanks in advance!
