I think the idea behind Lights Out is fine but both times ive used this crimson effect it has been VERY underwhelming. I think the trade off for having no vibrant beacons at all for the rest of the run is a massive downside for only getting +2 pulls per challenge. This is especially true when other crimsons give rerolls and sacrifices which in many cases are more valuable and have less downside imo. I think there is a lot that could be done to make this a more appealing option and I just wanted to spitball a couple ideas I had for it.
Idea 1: Make it so the downside of the beacon is present for a set amount of challenges. The numbers I had in mind would be about 15-20 challenges.
Idea 2: Instead of giving a flat +2 pulls per challenge make it increase the amount of pulls the longer the run goes. Something like every 10 challenges it gives an extra +1 pull. If the effect is too strong the amount of pulls it gives by default could be 1. Example - pick up lights out on challenge 30 -> gives +1 extra pull per challenge until 40 -> gives + 2 extra pulls until 50 etc
Idea 3: Make it so Lights Out would only take away rainbows and the effect of any active rainbow beacons but still allow players to find vibrant beacons if theyre lucky. Probably my least favorite idea but a buff is a buff.
