The Tear of Dhakaan

Extremely long quest with 6 shards to collect. It's not a run and dump quest. There is one rune that needs INT 22 or 23, one rune that needs WIS 20-21 (failed at 18 suceeded at 21), and lots of traps, some double. Many hobgoblins and Warmages (think buffed Cleric) on the way, and the odd bit of swimming!
