I am pulling together some information on Siege specifics and am not finding a place to put it so I am going to start here.
With the additional arms lore bonus, unraveling special wood weapons has a slightly better yield.
Unraveling at QF with a gargoyle:
Exceptional Oak Bow: 5 MR
Exceptional Ash/Yew/Frostwood: 3 MR
Exceptional Bloodwood Bow: 1-2 EE
6 non-exceptional bloodwood bows: 8 EE (1.3 per)
54 exceptional bloodwood bows: 67 EE (1.24 per)
I ran a larger sample and my result seemed to trend toward one essence per 4.4 bloodwood boards.
All bloodwood bows unraveled to EE at the QF. Rate of return for non-exceptional is likely an anomaly and I would guess that rate of return variance is based on durability as we have seen in other testing. Conversion rate appears to be approximately one enchanted essence per 5.5 bloodwood boards using bows. Since exceptional doesn't matter, the rate of return should be better making bokutos.
