As of the current update in RuneScape 3, players do not have the ability to manually decant certain types of flasks and vials. This includes potion flasks, crystal flasks, ogre flasks, powerburst vials, and calquat kegs.
Decanting refers to the process of transferring the contents of one container into smaller doses or into a different type of container. In the case of flasks and vials, decanting would involve dividing the contents of a full flask into smaller doses, such as potions or doses of powerburst. This can be useful for players who want to have smaller doses of potions on hand or for sharing potions with other players.
However, in the current state of the game, this manual decanting feature is not available for the mentioned types of flasks and vials. Players are only able to decant certain types of potions, such as regular potions and combination potions, at specific locations in the game.
It’s worth noting that the inability to manually decant these flasks and vials does not mean they cannot be used effectively. Potion flasks, for example, still provide the benefit of storing multiple doses of a potion in a single flask, reducing the need for inventory space. Crystal flasks offer increased crafting experience when used to make glass items, and ogre flasks are used in the Herblore Habitat activity.
While the lack of manual decanting for these items may be seen as a limitation by some players, it is important to remember that game mechanics and features are subject to change over time. Jagex, the developers of RuneScape, regularly release updates and make adjustments based on player feedback and the evolving needs of the game.
As of now, players do not have the ability to manually decant potion flasks, crystal flasks, ogre flasks, powerburst vials, or calquat kegs into smaller doses.
