Elemental essences
All elemental essences share the same 15 seconds cooldown and you can always have only one active at the same time. They offer nothing else than boosting your elemental penetration as they're meant to be used to help you counter enemy resistances during the fight. Elemental essences cannot be bought, nor crafted - they have to be collected from elemental nodes. You can get essences only of a specific element out of these, based on the zone's biome (E.g. you can obtain Standard storm essence only in highlands locations).
There are 3 tiers of elemental essences with great differences in their strengths.
Tier 1 - Increases your elemental penetration by 10%, can be often found anywhere around the open world.
Tier 2 - Increases your elemental penetration by 15%, can be also found around the open world but in zones that are crowded with enemies.
Tier 3 - Increases your elemental penetration by 20%, can be found only in dungeons.
