I feel like poison (the status effect) was never good in FF4. Bio is very good in FF3 (as a damage spell due to its general neutrality) but it kinda got nerfed for 4, and the actual poison status effect seems to barely work.
First time I remember poison actually doing any appreciable damage was...FF6 I think?
It gets better at some point cause I know the final boss of FF13 is totally obliterated by poison status. Considering how hard people say that fight is...bring poison. I think it did like half the damage over the whole right when I did it.
Just got FFIV 3D on phone this afternoon (which I'm guessing is the steam port) and yeah it's pretty lazy. Good to have a phone game though, been a while. Last time was Dragon Quest 6 back in like Q4 2019. Phone is so convenient of a platform if you don't mind the controls. Either way this version of FF4 is so jank. Turned the difficulty up to Hard cuz I want the real DS level Proto Babil. Dunno when I'll actually do this though. Probably chip at it over time. It's gonna take way more time than the PRs. Octomamm was like a GD superboss fight and harder than anything in FF4 PR, and it's like, the second boss.
