I thought it'd be interesting to share this here! This post is from a community event in Reddit Pixel Dungeon that often gathers hundreds of votes, and the event is finally completed just a few days ago. The highest votes on what people think is weak (or boring/lame) is featured in this image, and it's a good way to measure what the community thinks overall.
I'd love to post the huge amount of comments and discussions to Lemmy, but it might be better to just visit the Reddit posts. There's some deep and interesting discussions from the community on why these things suck. The second-worst items that gained significant votes may also be worth looking into: chaotic censer, unstable spell, death mark, magic missile, transfusion, unstable enchant, etc
Regarding Chaotic Censer, I personally think recent updates have made it usable at least. It sucks when it destroys loot and wrecks players in cramped spaces, but the fact that it now shows the gas + direction before it activates, it's a good improvement. At least players won't be at the mercy of RNG deaths and we can adapt to the situation with the tools in our bag.
Yup, I agree it can be good! But I think its main problem is that it's only good in a vacuum, but when compared to other upgrade options or wands it's inferior. It needs tons of SoUs for reliable corruption, making it hard to use especially with forbidden runes, and spending one charge + turn to give one random debuff is generally not worth it, as you need luck to find the right debuffs for the current situation. Other wands like lightning can just simply kill things immediately instead of debuffing, personally I think wand of corruption needs to be a good debuffer in the first few hits before it corrupts?
As for my personal pick for worst wand it has to be transfusion, I mostly just use it to prevent eye beams, maybe some small shields. It has its uses but I prefer blastwave or fire!
Yeah, transfusion is hot garbage.
Corruption gets good when the staff gives you plenty of reason to dump a bunch of upgrades into it.
