Mastodon Boss with parry

I like the parry skill a lot, but that elephant boss in the Mastodon badlands is a complete mystery to me as to which animation is parryable.

Sometimes the head swings can be parried, sometimes they go right through. Some other weird animation that I thought was a normal attack, but turned out to just take my HP right off without triggering the parry. Some really janky hitbox interactions with the parry window too.

There's also a spider enemy in this zone that does a small slam that looks completely identical to its normal attack, but it's actually a projectile attack that actually can't be parried(???) at close range??

Huntress would be much better if these strange inconsistencies were fixed.
