Alchemical Hydra troubles

[toxic dawn]

I have done about 500 kc without trouble but I've been running into an issue where the red phase doesn't get weakened using my usual tiles. I tried going one tile closer to the wall to pull it further but even that doesn't seem to guarantee it getting weakened. I checked the wiki and can't seem to find anyone experiencing something like this. Am I just experiencing skill issue of a colossal scale? I have experienced the same issue using both ranged and melee using the tilepacks from the plugin shown.

I just want to turn my brain off and do some hydra but everytime hydra goes to the middle and isn't weakened makes me so mad.

its not color coded per phase but theres some videos floating around about this method

I'll try them and let you know thank you

Are you highlighting hydra and watching to make sure the vent is somewhere inside the outline box?
