Fun and since you have so many runes the Godrick fight isn't so luck based. It can be if you decide to go into the fight with less health to save time but if you have full hp, it should be very easy.
Honestly I enjoyed this speedrun way more than the any% runs. Its less luck based and more skill based so when a run gets messed up, it feels like my fault and I dont get as mad.
I already have ideas on where to save time since my movement in this is messy. Also tanking 1 of the birds in the 10th rune area is probably faster than dodging it since 3 birds wont be on screen and it will reduce the lag a bit.
