By drinking this Essence you'll gain access to your own Training-Pocket-DimensionTM; Purgatory.
"Purgatory is designed to make you stronger by providing you with strong adversaries regardless of how mighty you become.
*By default, it is a bleak, rocky surface with cliffs and mountains. You, however, can change its design to your liking.
*Be it jungle, desert, a large city or flying island range. Your creativity and Purgatory's size are your limits.
*This also extends to the enemies you'll be facing. You can design them in detail or think of a general template like human, wolf, destroyer of worlds, etc.
*The dimension grows larger when you reach certain thresholds. If you grow strong enough to affect whole continents it becomes a planet, if you can affect a planet it becomes a solar system and so forth.
*The strength of time dilation is yours to decide upon every entry.
*To access it you can either teleport to it directly or open a portal if you want to take someone with you. People you take with you will also benefit from Purgatory's special perks.
*Bringing other people with you to train activates dynamic difficulty so everyone involved can enjoy a nice challenge.
*If you defeat an enemy in Purgatory a part of its strength becomes your own. If this enables you to gain new abilities is up to you.
*You can decide to enter a specific training mode to focus on a single aspect of you like your speed or magic. Alternatively, you can train a specific weapon or skillset. Purgatory will provide you with enemies that fit the thing you're training.
*Should you want to train with equipment you don't possess, you can let it be spawned somewhere near you at entering. Spawned equipment cannot be taken outside however.
*If you don't possess the basics of what you're trying to train, you will automatically be equipped with it. Only the theoretical knowledge though.
*Once you've acquired a firm grasp on the basics, further technical growth will come naturally to you.
*You can somewhat change the difficulty. Although there will always be a challenge, you can crank it up to eleven for a hellish experience should you desire.
*By default, you will not require sustenance nor age while inside.
*Should you die, which is not unlikely, you will respawn at a safer point. All your destroyed equipment will be repaired upon respawning.
*Purgatory is a place to grow and become stronger and not your summer house. Should you relax in one place for too long, waves of enemies with increasing strength will come for you.
*Access to your Purgatory is yours and yours alone and cannot be prevented, taken away, copied, etc.
