Icicle Plate
From Pixelmon Wiki
An Icicle Plate is a held item that raises the power of the holder's Ice-type moves by 20%. When held by Arceus, its typing and its signature move Judgment become Ice-type, and it and any Ice-type move receive the power boost.
It can be obtained as a drop from Mega boss Pokémon, from Beast Chests and from chest found in Igloos with basement.
