Royal Gel is an accessory dropped by King Slime in Expert Mode. This item makes majority of slimes passive to the player. The player will not be harmed even if they attack the slimes.



The item seems to be useless to more advanced players, but it can be used as surefire protection during a Slime Rain. It also lets you ignore more powerful Hardmode slimes such as the Slimer if you are not well enough equipped for those enemies. This item is also useful if you are going into The Underworld on expert mode due to the Lava Slimes.
