Underground Tunnels

Underground Tunnels

General Information:
In Pirate King Online, there is an undergound tunnel system which connects the three season islands - Spring, Summer and Autumn Isle.
This system consists of two tunnels, both contain monsters mostly related to story quests, one of them contains a boss as well, and the other one contains an NPC relevant for Story Quests.
These two tunnels are Underwater Tunnel and Seabed Tunnel.

Underwater Tunnel:
Rumored to have been a water plant for the citizens of Spring Town, a massive earthquake killed all the workers inside.
The Tunnel has since become a maze which is filled with deadly Zombies, who are very hostile towards intruders.

Map:

As visible on the map, it contains some interesting sights.
1) Zombie - Hami , a very important NPC for later Story Quests.
2) Portal to Spring Isle (West), this is the only way to reach the western part of Spring Isle, where the boss Fox Sage is located.
3) Portal to Seabed Tunnel, one of the three ways to enter Seabed Tunnel.

Monsters:
The monsters encountered here are three different types of Zombies:

Zombie (Pong)

-The weakest Zombie. It has low stats, but its attack applies a poison effect.

Zombie (Gang)

-Very similar to Pong, it poisons whomever it attacks, but it has considerably higher stats than Pong.

Zombie (Hu)

-Possibly the strongest zombie, it has a unique AoE attack which deals magic damage. This means that the damage is reduced by the target's Spr.
-Since there are a lot of them, in some areas even grouped up, they make moving through the tunnel very difficult, it is advised to bring a cleric to remove the poison with recover and lead the way, since Clerics will hardly take any significant damage from Hu's attacks.

Seabed Tunnel:

Slightly bigger than Underwater Tunnel, this map contains very interesting and more powerful monsters, as well as a boss.
Getting to Seabed Tunnel is either done by enterting the portal at Autumn Isle (2870,2782); Summer Isle (3423,2988) or Underwater Tunnel (160,425).
This will lead to three different spawns, which can be observed on the map image below:

Seabed Tunnel is more convenient for moving in-between Isles, as it connects Summer, Autumn and Underwater Tunnel, from which it is simple to go back to Spring.

Monsters:
There's three types of monsters here, each with their own unique debuff, however, interestingly, they drop items which grant immunity to one other monster's debuff.

Cursed Water Fairy

-A monster with insanely high dodge and ranged attacks. Its unique debuff is very similar to the Seal Master's "Cursed Fire" skill, it reduces the target's defense. So at first, it might not deal a lot of damage, but with the debuff the damage will increase by a fair amount.
-Using Cursed Bone will remove the debuff and grant immunity to the effect for 5 minutes. #ProTip: The item also removes the Cursed Fire debuff, but it doesn't grant immunity to further casts.
-Item which removes a debuff that it drops: Arista

Baby Icy Dragon

-A monster with a ranged attack and incredibly high health. Its unique debuff is the same as the Hunter's "Frozen Arrow" skill, it reduces the target's movement speed. This skill will make the target run absolutely slowly and it makes going through the map harder because monster will be able to get more hits off.
-Using Tinder will remove the debuff and grant immunity to the effect for 5 minutes. #ProTip: The item also removes the Frozen Arrow debuff, but it doesn't grant immunity to further casts.
-Item which removes a debuff that it drops: Cursed Bone

Long Hair Crab

-A melee monster with very high attack speed. Its unique debuff is probably the strongest one. When it casts the skill, it will enwrap the target in a spider web, which will make it unable to move or cast any skills.
-However, using Arista will remove the debuff and grant immunity to the effect for 5 minutes.
-Item which removes a debuff that it drops: Tinder

Boss:

Icy Dragon

-A boss with powerful attacks, but it is extremely frail and dies fast. Although it has a variety of drops, the main reason why it's hunted is the fact that it's the only way to obtain a Twilight
