Walkthrough
Once you have spoken with the npcs, 4 locations will be marked in the mini map. They mark the location of boxes that spawn monsters if you get close. You must clear the spawned monsters in all 4 locations to proceed. Once all the boxes have been dealt with, you will fight against the boss EL1_A17T. There are 2 major mechanics to be aware of:
- Bio Battery - Must be destroyed by stepping on or walking beside it which triggers it to self-destruct.
- Destroying all 4 will unlock a special Reinforcing Energy npc that provides a powerful buff that gives +20 to all Stats for 30 seconds.
- If any of them survive after the duration, they will 'strengthen' (not exactly sure what it does) the boss.
- Chemical Poison - Must be avoided. If one is approached, they will transform into a chemical poison cloud that constantly deals poison damage to any nearby players as well as heal the boss. Multiple clouds can remain present overtime.
Rewards:
The following items are given as a reward for defeating the boss and from finishing the instance:
These items can be traded for various equipment via npc in @go exchange
Additionally,
OS Remodel Cube can be obtained at random from doing the instance in hell mode or higher. The item is used to convert any of the OS weapons and their headgears into their OSAD counterpart.
