Unfortunately no it doesn't. Currently the talent only works with the wand recharging and artifact recharging buffs specifically. Ring of energy is only for wands, artifacts, and hero armor abilities currently.
To the surprise of absolutely nobody, I'm closing the comments on this thread.
It's a rainbow colored potion wishing people a happy pride, it is as similarly inoffensive as any of the other holiday items, and will be gone in a few days. Obviously not everyone celebrates such a holiday, and that's fine, but If pride existing in the game offends you but halloween/christmas/chinese new years doesn't, then you should consider why that is.
Gold and hidden rooms are never contained deep into walls, there's no reason to dig more than 1 or 2 tiles out from a room in search of secrets.
The horn charges based on exp gain, not based on time, mainly to prevent people using an upgraded horn to stall out hunger forever. The amount of charge you get per hero level scales from ~0.33 rations to ~2.25 rations at +10. Each ration you put into the horn will be recovered after about 5 levels.
the main idea is that artifact levels aren't analogous to levels you spend SoU on at all. I'd honestly rather just change it back to the way it was before, where transmutation simply failed if you rolled all the artifacts.
Ring of wealth does a variety of things, one of which is that gear specifically dropped by it is more likely to be enchanted. You're probably upgrading it more for the gear drops themselves, and I don't plan on adding a trinket that directly adds equipment drops.
One thing that's worth mentioning for item tiers is that they create some strategy for SoU use, as there is a tradeoff between spending SoU sooner to not die immediately, and saving them for later higher tier gear. If weapons and armor scaled up with player level, then experienced players would just dump SoU on literally anything and win the game with it. This was actually a problem with Huntress before her rework in v0.7.1, as prior to that her unique item was directly upgradeable and experienced players could just win the game outright with it alone.
It depends a lot on what items you have. Generally upgrade/reforge/harden are better if you already have good gear, and smith is good if you need to fish for a good weapon or armor. Reforge, harden, and upgrade can each be used a second time, but the second use costs 1000 more favor.
Generally anything that isn't equipment can be used in the alchemy interface, but not all items have a recipe.
I was very happy with RoA when I first thought up the concept for it. I was mulling over adding a new ring but didn't have a great idea, and knew arcana was a winner the moment I thought of it. Enchants and glyphs have always been fun for players to use, so letting them access the power budget afforded to SoU allowed me to really heavily boost them.
It's worth noting that this game has nothing to do with Pixel Dungeon, and seems to just be trying to piggyback on its popularity by stealing its name.
