Items Potion of still blood

[Goblin Mage]

A potion that lasts for, idk 1 minute? it would depend on balancing
The effect stops buffs from counting down out while its active, effectively adding 1 minute to all buff potions

To balance it there might need to be a cooldown effect in the form of a debuff that lasts the same amount of time as the potion, so you cant keep drinking still bloods and keep your more expensive buffs forever

I think that inherently every buff item is farmable enough that adding an indefinite extra amount of time through another expensive, consumable item is, for the most part, fair.

This is a theoretical balance concern, but it can pretty have some interesting tradeoffs:

• The effect can apply to buff effects as well as debuff effects, so you are committing a risk/reward and saying you are willing to risk suffering through, say, an indefinite amount of Cursed Flames DPS to extend your Wrath and Rage Potions an extra minute. This also makes the Chaos State debuff technically permanent, as well as Potion Sickness and Mana Sickness, as they will never count down under this method. If it applies to debuffs, then removing the buff effect early would allow debuffs to count down.
• Applying a debuff that prevents the "early" use of the potion again, in case you get a debuff you don't want to suffer through and end the buff early. This then means if something goes incredibly off script you only extended your buffs by maybe 20 seconds, instead of a full 60.

However, since every other potion is farmable enough, I can't see a lot of contexts where I would actually use this, unless it opened up some other interactions such as taking Cozy Fire/Heart Lantern buff effects outside of their radius. All in all, not particularly a bad idea, but I dunno how well it would actually flow in gameplay.

When considering the balance concerns of extending a single Wrath or Rage Potion's duration, you have to ask yourself how much effort you're willing to put in to make them last an extra minute longer in comparison to just getting another Ebonkoi or Hemopiranha and making another potion.

I was thinking of this but it might make it too risky to warrant using
it could also be an interactable station instead of a potion, maybe the alchemy table gives you the still blood effect

Another implementation of this would be an area of effect furniture that slows down buff countdown when in it's radius, maybe also slows down debuff too depending on if that turns out to be too annoying or not

Honestly, just having an interactive station to extend buff durations would be best. It could be somewhat lategame, too, which would be interesting. You don't get much interactive furniture beyond the very start of Hardmode.
