Lilypad of Fertility

The Lilypad of Fertility is an item from the Xeno's Reliquary mod. Placing the Lilypad within a 9x9x6 area (vertically speaking, one block below, the block the lilypad is in and up to four blocks above the lilypad) next to crops will cause them to grow faster. It can be reliably looted from Battle Towers, most often from the top/final chest. While in an inventory or while being held, the Lilypad has the same shimmer as an enchanted item.

Their effects do stack, so if their areas of effect overlap, the plants in their combined area will grow faster. This can be used (though not reliably; a smart straw golem and wooden golem from the Thaumcraft 3 mod can be used to take the best advantage of this method) to condense your farm into a very small area by surrounding blocks of farmland with up to eight lilypads of fertility.

The Lilypad of Fertility can be stacked as high as 64.
