Absorbing Essence From Essence Extractors

Essence extractors are scattered around the map. Players standing in the extractor's area of effect will harvest its essence, until the extractor is depleted. Extractors will exist in three tiers — the farther away from the starting base and the closer to the center of the map, the more essence the extractors will contain. Players can only harvest essence once all NPCs in that essence extractor are defeated.
