Birthday Cake

"A gorgeous cake to celebrate Haven's first birthday. Builds up power as it is fed more ore."

Overview
Birthday Cake is an Exotic tier furnace that was first seen on Berezaa's Twitch stream on June 11th, 2016. It was released the next day for Miner's Haven one year anniversary.

The Birthday Cake functions similarly to the Kappa Investor, although a bit more powerful. The Birthday Cake is useful for processing one very valuable ore.

Trivia

 * The effect of the Birthday Cake is quite similar to the Kappa Investor, which starts at x0.5 and gradually becomes more powerful.
 * Coincidentally, both items are exotics.
 * This is often rivals with the Excalibur because of it's stacking multiplier.
 * The "MH" on the cake stands for "Miner's Haven".
 * This is the Fourth Exotic tier furnace after the Excalibur and Kappa Investor and The Sunken Past. After that, the Volcango and the Flying Dutchman and the Heavenly Wisp and the Blood Magic were added.
 * This makes the Kappa Investor somewhat obsolete, due to its multiplier being x100 instead of 64. Though taking long to get to x100.
 * This was available for 3 days instead of one due to berezaa extending the event for two extra days.
 * This is one of the eight furnaces with a special sound, the others being the Thingamajig, Dark Magic, Excalibur, The Fracture, Sage Redeemer, Pirate's Loot Collector, and The Sunken Past.
