Immunizer can be consumed from the Item Bar while in the field to grant the Natural Recovery Up Status Effect for five minutes. This buff increases the natural regeneration speed of recoverable Health, and is modified by the Recovery Speed Skill itself. In addition, Immunizer can also be used as an ingredient for crafting Ancient Potions, Might Pills and Adamant Pills.
Using an Immunizer after using a Great Sushifish Scale will overwrite the Natural Recovery Up buff duration, increasing it to 5 minutes.
