Prismatic Jelly is dropped by the rare Prismatic Slime. This guide will cover where to find these slimes and get yourself some Prismatic Jelly.
Similar to Ectoplasm, which is dropped by ghosts, Prismatic Jelly can only be obtained when the special order is active. The item serves no purpose other than to turn in to Rasmodius for a 5000 gold reward, plus either the Monster Musk recipe or Mini-Obelisk recipe.
Stardew Valley: Where to Find Prismatic Jelly
When you take on the special order, you will have seven days to find the Prismatic Jelly and bring it to the Wizard for the reward. The jelly will disappear after the order is complete, so there is no reason to collect more than the one. It is possible to get this same quest twice, but you’d have to recollect the jelly the next time anyway.
To get Prismatic Jelly, you’re going to need to collect a Prismatic Slime. You haven’t seen any of these up to this point, as they can only spawn when this quest is active.
Any time a Slime spawns, there is a small chance that it can instead spawn as a Prismatic Slime. A Slime has a roughly 1.2% chance of spawning as a Prismatic Slime, and daily luck can play a factor. They can spawn in the Mines, Skull Cavern, or the Quarry Mine.
They appear as the same shape as a regular Slime, but with a constantly changing color, and when killed, they have a 100% chance of dropping Prismatic Jelly.
The best place to search is between floors 95 and 115 in the Mines, as these levels are where the most Slimes will spawn. If you’re having trouble finding one, make sure you are playing at the maximum resolution, as zoomed out as you can, such that you can scout large areas more.
While it can be kind of annoying to find due to the luck involved, seven days should be more than enough time to stumble upon a single Prismatic Slime as long as you take the time to delve to get it.
