To the point, I'd like to say the Band of Regeneration should be buffed. You may ask why, but a quick comparison between some items with passive life restoration capabilities should make a small problem evident.
For easy comparison (non-accessories listed for sense of scale)*:
The Band of Regeneration, and even its Hardmode upgrade the Charm of Myths, are both dedicated passive health restoration accessories that only exist for that express purpose. Their capabilities are matched or eclipsed (no heavenly body pun intended) by numerous jack-of-all-trades across-the-board stat boosters. The weakness of the dedicated accessories means there's very little reason to pick them over other accessories beyond availability. The main reason anyone with knowledge of these rates even considers wearing a Charm of Myths is for the potion cooldown effect; the health regeneration is just an almost negligible bonus.
I'm not entirely sure what rates would be more acceptable, because life regeneration has been a hot topic of debate on these forums for a variety of reasons *coughheartlampcoughspectrearmorwheezevampireknivescough*. What I do know is, items dedicated to a task should be more powerful with respect to that task than items that provide a "minor increase" to numerous stats. Whether this means switching the rates of the Sun-Moon-Both stones with that of the Band of Regen family or buffing the Band of Regen family proportionately with respect to their position in game progression doesn't matter to me and is up to the community and ultimately this game's lovely development team.
Buffing proposals from community:
- Make it similar to the mobile version's Valentine Ring (50% regeneration rate)
- Heals 1-2 health per second rather than 0.5
- Global % increase to all regeneration sources (25%?)
Additionally, I've always seen the Band of Starpower as a counterpart to the Band of Regeneration; one restores mana while the other restores health. This dichotomy falls apart however, due to the fact that the Band of Starpower is a Corruption exclusive item while Bands of Regeneration are littered around the Underground in every world. I feel that it would be thematically appropriate to make the Band of Regeneration a drop of the Crimson's Demon Hearts, considering the Crimson has both a gear and color association with health, while the Corruption has a slightly closer association with mana. The Band of Regeneration even has a heart on it, further fitting in with the Crimson's theme!
Unfortunately, the current Mana Cuffs and Mana Regeneration Band recipes would then go from a Corruption world-only items to multi-world scavenger hunt items. This could be fixed by changing the Mana Regeneration Band's recipe to require infusing the Band of Starpower with a Mana Regeneration Potion instead. I justify that accessory-potion combination both with the existing accessory-potion combination, the Mana Flower, and by imagining that the potion was poured into a hollow cavity of the Band of Starpower to increase its mana channeling capabilities, similar to how the Mana Flower is just a Nature's Gift soaking up a Mana Potion. It never made sense to me that the Mana Regeneration Band just rewrites the Band of Regeneration's effect entirely, and this would resolve that small issue as well. This would additionally encourage the player to explore the alchemy side of the game. To further preserve the upgrade dichotomy between the two bands and biomes, Baconfry's Blood Pressure Cuffs could be implemented as the counterpart to the Mana Cuffs as outlined in the linked thread. Alternatively, for the mage alternative, the Occult Thorn would serve a similar purpose to the Magic Cuffs.
To clear up any confusion, this would be the result for the drop tables:
This doesn't have to mean that the Crimson would never get a light source utility item either, a sixth item could easily be added to both of them that would finalize the 1:1 item category correspondence; a second Corruption accessory and a light source for the Crimson. What those items could be is up for anyone to suggest, it just makes more sense to me to have the counterpart bands found in counterpart biomes of the same color themes.
When considering this part of the suggestion, bear in mind that you may simply be accustomed to where the Band of Regeneration currently is; if the Crimson had existed from the start and the Band of Regeneration was already a Crimson exclusive, would you propose for it to be moved to the underground gold chests while the Band of Starpower was still in the Corruption? Are the gold chests more thematically appropriate than the biome of blood? Moving the Band of Regeneration to the Crimson certainly doesn't make it any harder to get ahold of if you need one, and in fact allows you to find it more easily since you know where to look.
Alternative proposals for matching counterparts from community:
- Remove the Band of Starpower from the Corruption, making both non-biome specific without changing recipes
When this game first came out, the Band of Regeneration was one of my favored accessories. I enjoy items in almost any game that involve life manipulation, whether through restoration (holy or vampiric) or as fuel for dark magic, and the Band of Regeneration, though simple, was no exception. I enjoy the concept of the Charm of Myths as well, but as the game currently is, those two items pale in comparison to the myriad of other options available. It just feels like the Band of Regeneration has been left behind in the storm of item balancing and additions; a pristine relic of Terraria's past.~ Closing ~
TL;DR - Please buff the Band of Regen and Charm of Myths, and make the Band a Crimson drop to match the Band of Starpower.
