Warblade class description states:
Check your initiator level on the table (level 6) and you can learn any maneuver within your disciplines of up to level 3, assuming you meet the pre-requisites. You can take a maneuver, and then immediately use that maneuver to qualify for a different one, as you get to apply them in the order most advantageous to you.Originally Posted by Maneuvers, p21 ToB
swordsagedwarbladed. But I'll answer your question, Andezzar.
A164 You are correct in the first method, but the second method costs 23,000 gp (total).
First method uses Table 6-11, page 234 MiC. Applying a +1 Deflection bonus to Ring of Invis costs 2000 gp. The second method, applying invisibility to a ring of protection, costs 21,000 gp additional. See page 233 MiC. If the added ability costs more than the cost of the item, you add the base cost + 1/2 the cost of the item to be enhanced. So you'll spend an extra 1000 gp doing it the second way.
