Item:Lightning-Split Soarwood

Locations for Farming
This is probably toughest collectible to get, looking for information about good drop points.
 * Haunted Library - 1 in key room, 1 in falling floor room
 * Chamber of Insanity - go right, clear the room and continue
 * Lair of Summoning - take left, don't activate trap in the room, get table and d-door out
 * Ruined Halls - have to get gargoyle lever first, bookshelf at shrine door, 2 tables in intel room
 * Xorian Chiper - when you do gird runs, you can check crude altars in golden/iron key room as well
 * Splinterskull - table in the throne room gives you a shot at one, and it can be hit 7 times on a run (don't forget to clear the throne room on part one, too). It's also possible to re-run the first half of part 6 over and over.  Don't kill anything: just run, grab collectibles, and open doors.  Since you technically complete the first part each time, you can immediately do it again.  Seems to be a very rare drop, though.  Good news is you might also pick up a Silver Flame Hymnal on the first bookshelf, and another good drop is Fragrant Drowshood near the second Shrine. There's also another more out of the way one, where Whisperdoom spawns.
 * Deleras 2nd part - crude altar in the very last room, where you first fight the shade of Deleras.
