Goblin Omelette

Goblin Omelette is a drill upgrade module that costs 99 Goblin eggs and generates 1 fuel every 20 seconds.

The craft is unlocked in The Forge upon reaching Heart Of The Mountain Tier 4.

It takes 1100 hours to refund the cost of creating this upgrade. (3 fuel per minute = 180 fuel per hour. 99 Goblin eggs x 2000 fuel each = 198,000 total fuel. 198,000 fuel / 180 = 1100 hours)

There is currently an issue that when the player is mining a block while gaining fuel: the nbt updates and it resets the block breaking, making it less useful.
