MapleStory/Zakum

Zakum is an easy boss because even though every couple of seconds he drops the entire party's HP and MP to 1, it has relatively low HP. This means that the entire party will need to have many potions to survive as they may die due to its attacks if they are fighting the normal and chaos mode versions, since easy mode attack damages are low and they are usually not fatal.

Zakum's room is located at the end of the Dead Mine, at the furthest point from El Nath. In GMS, Zakum runs can only be completed twice per day by each Party Leader acrossall modes.

Pre-requisites

Level 50 or higher for Easy mode.
Level 90 or higher for Normal and Chaos mode.
Maximum 2 entries per day regardless of mode.
Minimum 1 Eye of Fire for Normal and Chaos mode (Eye of Fire Debris for Easy mode). Can be obtained from NPC Adobis.

Simple preparation tips

Ensure that you have All-cure potions ready as zakum can cast its full-map lightning attack which can seal skills. To reach Zakum's Altar you can simply go to Chief's Residence and talk to your 3rd job instructor NPC to teleport to the Door of Zakum. Talk to Adobis to obtain Eye of Fire. You need an Eye of Fire to go through the door as well as to summon Zakum.

Repeatable Quests

Note: These quests are not required to be completed to fight Zakum. You can do these quests for fun though and it awards very little EXP.

Adobis Mission I

When you first reach Adobis,

The party can consist of 1 to 6 members. The time limit is 30 minutes. The goal is to collect 7 keys. Additionally, the party has the option of collecting 30 document pieces. Once inside, there are 15 doors. Speed and Teleport do not work here. Each of these leads to a room which is made up of 1 or two parts. Inside rocks and treasure chests are scattered on the floor. These must be destroyed to get the Keys or Documents. Documents are always found in rocks, and Keys are usually found in Chests, though there are exceptions. A small note, the word Documents is blocked in game, so they're usually referred to as "Docs".

Unknown Dead Mine

Once you enter stage 1, you will be in the room displayed on the left, with further rooms accessible as labelled.

Two rooms, 10 and 7, lead to a further room called Area 16 <A Dead Mine Somewhere>, which has 6 rooms branching off of if. The arrow in the diagram will lead back to the main area.

Documents and keys are always found in the same rooms, listed below, but the specific rock or chest is randomized. Documents are generally found in rocks, and keys are generally found in chests, unless otherwise noted.

Room	Keys	Documents
Entry	0	3
1-1 1-2	0 0	1 1
2-1	0	1
3-1 3-2	0 0	1 2
4-1 4-2	0 1 (rock)	0 1
5-1	0	1
6-1	0	1
7-1 7-2	0 0	1 2
8-1	0	2
9-1 9-2	0 1 (rock)	1 2
10-1 10-2	0 0	1 2
11-1	1	1
12-1	0	1
13-1	0	2
14-1	1	1
15-1	0	1

Room	Keys	Documents
16-1	0	0
16-2	1	0
16-3	1	0
16-4	0	1
16-5	1 (rock)	1 (chest)
16-6	0	1

Once all the keys are collected, they must be combined into one stack and dropped onto the large treasure chest located randomly at 16-5. For this reason, it is best to get the key in room 16-5 last. This causes the chest to open, and a complete Fire Ore is released. The Fire Ore must be returned to Aura located in the first room.

There are more than 30 documents, so get the ones that are easiest. It's recommended that one person focus on collecting keys while the others gather documents. Once everything is collected, hand it in to Aura, and walk through the portal. Anyone who does not make it through the portal will not receive a prize. Additionally, the leader must exit through the portal last, or the party members who had not yet passed through will not receive prizes.

Although it is fastest to complete with a larger party, it is possible, but much slower, to solo the quest.

Rewards

If completing the quest alone with just keys, the reward is 12000 EXP. If completing it alone with both Keys and documents, the reward is 20000 EXP. If completing it in a party, even if it is only made up of two members, with only keys, the EXP is 15000. If the party has both Keys and Documents, the reward is 20000 EXP. Any time that all Documents are collected, all players who finish are awarded with 5 Return to Dead Mine Scrolls.

Zakum Jump Quest

The second part of the Zakum Quest is a very long linear jump quest which requires the player to reach the end. Here, there are miniature statues that spew quick moving fireballs hindering the players progess. Below is a massive lake of lava therefore should the player fall, they'd be taking in a lot of damage getting back. Players cannot enter the Jump Quest until they completed Adobis's mission (the 1st Stage).

Zakum Boss Fight

Location: El Nath, Last Mission : Zakum's Altar
Summoning Requirement: Eye of Fire

This quest involves a giant stone boss at the end of The Caves of Trial. In order to face this huge boss, it is required that the players speak to Adobis to obtain the Eye of Fire. The boss has eight arms which all need to be eliminated in order to take out the main body, you also have to fight the main body three times. To kill Zakum you need a party of at least level 100 people, with a good mix of classes, especially priests. This boss is considered one of the easiest boss in all of MapleStory. Zakum is based on the Muslim belief in Zaqqum, a tree said to grow in hell which provides the only fruit that the damned may eat. This is consistent with the Zakum of MapleStory, as a giant tree can be seen in the background when fighting it, and it must be summoned with a "seed". The boss is supposed to be the physical representation of this tree.

Tips'

Closing ALL Programs and lowering your resolution is a definite must. Zakum has a tendency to majorly lag/DC people.
Have a decent computer processor, graphic card and RAM. People are known to DC even if they have usually lagless connections, as the image frame loading is extremely high.
You may enter the room with Zakum twice a day. The party will be moved in simultaneously when the leader clicks to enter.
An Eye of Fire is required to summon Zakum, which can be received from Adobis.
Easy mode Zakum will be much easier to kill if both of the top arms are killed (reverses control and dispel), along with the status arm (3rd from top at the left side, which casts abnormal status) and the healing arm (3rd from top at the right side which heals 50,000-55,000 HP for all remaining arms at the point of time of heal every 30 seconds.) Avoid touching the poison clouds as they deal 1500-2500 damage, as well as the body when all arms are taken down since it still deals high damage.
Normal and Chaos mode Zakum will be slightly easier to kill if the healing and status arm (third from top, left and right) are destroyed first. Healing arm (third from top at right) heals Zakum 50,000 to 55,000 HP about every 30 seconds.
Meso explosion may cost lots of mesos but can save lots of time if you leave the physical arms and get chief bandits to drop mesos while people kill the remaining arm.
After all the arms are down, Zakum begins summoning monsters (Boogie, Puco, Pachu, Punco, Cuzco, Opachu)and drains HP and MP to 1. Avoid touching the body as it deals high damage which can easily kill. (for normal and chaos mode; deals regular damage in easy mode)
For chaos mode, ensure that you dodge the red falling pillars at all times as it deals 50% damage, which means if you were to stand in between 2 pillars you will instantly die as the damage bypass any invincibility, unless your maxHP is an odd number or you are standing at the top half of the map.
Easy mode Zakum has 3,864,000 HP in total and gives 130,000 EXP when killed. Normal mode Zakum has about 120.5 million HP in total and gives 7,993,800 EXP in total. Chaos mode Zakum has about 11 billion HP in total and gives 19,414,800 EXP in total.
Easy and Normal mode Zakum drops the Zakum Helmet 1 (2 in JMS) when defeated at a chance (easy mode has a lower chance than normal mode). Chaos Zakum drops the Chaos Zakum Helmet at a chance, which is more powerful than Zakum Helmets.
