What you do, is take a fairly high Necromancer (best for a "bone-mancer") that hasn't put any skill points into the skill "Bone Prison".
Equip him with a pair of Marrowwalk Boneweave Boots and bam, the glitch is done. The "Level 33 Bone Prison (13 Charges)" instead of giving you charges, gives you +33 to Bone Prison!! This is a massive boost for any of Bone Prison's syenergies, such as Bone Armor or Bone Spirit.

Step by Step.
Have a necromancer
Do not put even 1 point into Bone Prison
Level him to lvl 66 (boot's req)
Necro must have at least 118 str (with or without items)
Equip the Marrowwalk Boots
Add all the points you want into bone spirit
Keep on lvling...
Note: DO NOT ADD POINTS INTO BONE PRISION, OR THE EXPLOIT WONT WORK ANYMORE AND YOUR CHARACTER WILL BE RUINED.
