Hello,
I would like to propose a new usage for Vials of Blood. I've gone ahead and run this idea by some reputable players prior to making this thread and it has received an overwhelming amount of support, so I decided to bring it to the forums. Please read the whole suggestion before coming to a conclusion.
Now, what I'm proposing is that you are able to destroy vials of blood in exchange for X amount of blood runes. Or, alternatively, you can use pure essence on vials of blood in exchange for X amount of blood runes.
The only way to obtain Vials of Blood is through the Theater of Blood. They're an uncommon drop and you only get ~40 vials per drop, meaning that players don't usually have too many on hand. Furthermore, they're used for charging scythes, sanguinesti staves, and making bastion/battlemage potions. Given this, players will have to think twice about mindlessly exchanging all of their vials for blood runes.
Normal players already have access to an unlimited supply of blood runes through the store, so this update would be particularly helpful for ironmen (especially given that a vast majority of the players that run ToB are ironmen) and more so for those that have blood weapons that need charging. Yes, the theater already drops bloods, but the drop is uncommon, so the runes don't add up very quickly at all. Given all of this information, I see no immediate drawbacks and this update would be huge for ironmen. This is not a feature in OSRS but given that It's a private server, I think it'd be very fitting.
Thanks for reading!
