Fire Underground

What to do
You will be recharging defense Stations with Small Red Crystals from the Crystal Spawn Room by the entrance and Large Red Crystals found within the complex.These defense stations kill the Fire Demons ( Lvl 33-48) that spawn throughout the complex, you will need to reactivate at least 29 out of the 35 stations.

In the process you will meet Ruby (219,112) at Station 20, who wants a large Red Crystal (Get it N of Station 18).

There are 5 books of Ancient Knowledge to be discovered.

There are Fire Golems to be killed and their blood collected in special containers ( found NE of Station 12 ).The Blood is used to solidify the Lava so you can walk on it. Red Numbers indicate how many units [1-5] of Fire Golem Blood you need.

DO NOT GO BEYOND THE LAVA WITHOUT A RECALL SCROLL ,      IU Exit is Arch Only

The commander informs you that soldiers are available to assist you.

Use TAKE to recruit them, DROP to return them and get exp.

They obey a limited set of commands :

Follow,     Makes them follow you.

Front,       They walk in front of you.

Retreat,     Follow you more closely.

Back,        Makes them move 1 step back

Behind      Attack enemy from behind, (The Fire Golem Killer)

Fire Underground XP cap
After completing the missions, you are asked to explore and report back any stations you find.

Each station gives 8,000 Exp. The cap is the amount of exp to get from your current level to the next / 5.

For example, A level 40 needs 265,761 exp to get to level 41. 265,761 / 5 = 53,152.The level 40 could get 6 stations uncapped worth a total of 48,000 exp but the 7th would be capped and any extra stations would give no exp at all.

Here's a list of max stations you can hit before cap for levels 30-40.

30 - 2 Stations

31-33 - 3 Stations

34-36 - 4 Stations

37-38 - 5 Stations

39-40 - 6 Stations

AK here give you 3.750 exp.

Keep in mind, the higher level you are the more stations you can grab at once. Use the formula above.
