I had the stupid idea that golems would distract moder since the drakes attack them and went into the fight with 2 nearby golems... Bad idea, spent over half the fight repositioning to get out of the way of 3 attacking enemies. Luckily drakes eventually pulled one of the golems away and led it back to its home in a nearby mountain. There were a couple choke points in the area that allowed me to melee moder on the ground while being chased by the golem since the golem could not walk through moder to get to me, this saved a ton of arrows. When night hit the fight actually got easier as the wolves distracted the other golem for a time allowing me to actually 1-on-1 moder.

I feel like moder's health has been tuned down since my last playthrough. Last time I needed 2 bows to take down moder even with opportunistic melee assaults, this time my fully upgraded drauger bow had about half its durability left and I did not deplete either my obsidian or poison arrows. However, running from the golems during the fight made it the longest boss fight I have had.
