This summarized page lists in-game items or topics best summed up with a single wiki article. This is so we can avoid making dozens of pages all dealing with slight variations of the same thing. If they are created at all, the individual pages should all redirect here.
There are many different potions that replace Health (HP). Most replace an amount immediately and then a smaller amount each tick over a period of time. These are called Heal Over Time (HOT) potions. The second, rarer, type heals a large amount instantly. Instants usually heal more but if the amount healed is more than you need the extra is wasted, while HOTs repair the damage as it is still coming in, tending to waste less. The third type of Health Potions are the Phirius Potions, which heal a % of your Maximum instantly. Each type (HoT, Instant, and Phirius) uses a different timer for cooldowns so that it is possible to use 3 different potions to heal your Health or Mana at the same time.
The following Categories should be of interest to you:
† All Phirius Potions may be found inside of chests in Minigames, rewarded by events during a Festival, or purchased in the Item Shop (sometimes). Additional sources may be noted.
You can upload an icon for this item to File:Icon - Health Potions.png or link to an existing icon from File:Icon - Health Potions.png using code like #REDIRECT [[File:icon_filename.png]]. The icon should be in PNG format. You can override the default name using the iconname field of this template (not advised as it negates the automatic display of the icon by the itemlink template).
As with all Alchemy Recipes, the Crafting Cost represents the cost of the glassware plus any cost to use the Crafting Station (as displayed on the Crafting UI).
Very few Crafted items have no upgrade path, but this appears to be one of them.
