I crafted some new wraps for this. absolute min lvl 20 holy burst silver GEOB. Only thing is that they dont bypass DR!!!! Seems as though the silver is broken on the new high lvl wraps. Didnt find out till part 4! So I'd guess it slowed me by about 90 minutes. Part 5 was crazy, no DR breaker and my armor broke in first minute of fight.
638 heal scrolls (used over 5 attempts, not sure how many for final completion)
about 300 haste pots
3 box of chocolate
12 deathward pots
25 lasting haste pots
