Irrlights.
Why on earth the bonus to irrlights was added I have NO idea since they are a terrible, useless curio and even irrlight lanterns are practically useless too.
If irrlights were buffed in a meaningful way it could help to balance the Blacksmith credo nicely.
The first and most obvious way to do this would be to make them an actual decent curio. The base LP of them could easily be doubled, tripled or more, or stack the base lp 10 times higher and make the study time higher too. As it stands right now there is practically no scenario where they are worth studying consistently, which makes the idea of getting more of them as a bonus completely retarded.
The second obvious way would be to make irrlanterns capable of actually lighting shit. Simple, easy, effective.
The third way is an idea I came up with. If irrlights are spawning often, what about making a rare variation of them similar to a ruby dragonfly chance?
Make us WANT to try to pick them all up and be EXCITED about them spawning more often.
This rare variation irrlight could have an additional function, besides being an even better curio, it could have a despawn timer and the ability to PROSPECT ORES on THE SAME LEVEL YOU ARE ON.
This would be a brand new bonus function that could really add an interesting dynamic to the game and if they have a despawn timer like a mandrake it wouldn't be something that can be overpowered and abused. It would be like a "oh shit, I got the good irrlight, time to drop what I am doing and go and use it" type of thing.
Maybe it can have a limit as to how many times it can be used and then the irrlight is spent or degraded in to a normal irrlight. Maybe the quality of the irrlight has some meaningful input as to how far you can prospect as well, but overall the idea of having a temporary bonus upgrade to the new very short-range ore sensing of Miner credo sounds like a pretty intriguing bonus.
