So a thing i noticed when i played a few games of Dual daggers shade earlier was that for some reason a number of my attacks from behind the boss would seemingly randomly miss. I decided to check this one out and here is what i found :
No wonder i struggled to hit the troll! The distance you see between me and it is actually the closest i could walk up to it, any closer and there was an invisible wall blocking my passage. And my daggers could not reach him from there.
For context of this image i was testing in the modded realm with the mod for damage numbers and as you can see here, i am at the end of a heavy attack behind the troll ( as close as i could get) and yet there were no numbers, the attack had missed.
So the bug here seems to be a case of the hitboxes being ridiculously fat!
But that said it was very inconsistent and sometimes i could walk a little closer and other times the attacks would hit from that distance. I have no idea what the heck was going on for certain. But i am sure it was taking effect in game too and not just in the keep.
Troll and spawn both have this going but the stormfiend doesnt seem much affected as i could approach without issue.
