Slayer of Teneshpar

Also, if you couldn't be present at the event, or you are above 80, you have the opportunity to face Teneshpar during mini world change "Devovorga Essence" exchange 8 Tentacle Piece with npc "Dread Guardian" in Vengoth. You will have to face the creature alone and with a time limit of 10 minutes.

After killing, you will get the achievement Slayer of Teneshpar

(It is no longer so impossible for Knight and Paladin to face this creature with certain strategies.)

When that world change is, NPC Towncryer will say: "Hear ye! Hear ye! Use Devovorga's Essence to fight an evil presence! Trade your every tentacle piece, to enter a boss' lair with ease!"

Or also you can check in World board, using an adventure stone in any temple, and will say "In case you have some spare tentacle pieces, you can now use Devovorga's very essence to enter a boss lair!"

You can unlock this achievemnt in 2 ways:

1. If your are level 40-80, then you can access the portal on the east side of Folda and do alot of damage to Teneshpar during the Rise of Devoroga world event.

2. (If you are above 80) is to wait for the Devovorga's Essence mini world Change and exchange 8 [We do not have this item]at the portal in Vengoth to have a one on one battle with the boss.

However since 2014, this boss was given an incredible healing boost, making this achievment LITERALLY impossible for Knights and Paladins to unlock, as the damage they do isn't even comparable to the health healed by the boss.
