Armor Reduction

The Armor Reduction mechanic was a Event Only Mechanic that was introduced in the Summer 2015 Event and then later into the Fall 2015 Event. Within these events, these mechanics introduced a challenge that made players attempt to perform different tasks which they were requried to clear a certain requirement to help reduce the Abyssal Boss's Armor. Most abyssal bosses during these events were given high armor which made it very difficulty to defeat them without exploiting the gimmick that would weaken them. While it was quite possible to defeat the bosses without exploiting the gimmick it was very difficult to do so.

Within the events, each of the requirements needed to defeat the boss changed so no two gimmicks were the same as of this point. But one thing was made clear from each event which was held, there was a method to weakening the boss and the boss's defense was set on a timer and would reset if enough time had passed.

Summer 2015 Event - Operation FS E-7

Fufu...you came...? Hee... you came...
The Air Defense Princess, the first boss to be introduced to the Armor Reduction Mechanic

The Summer 2015 Event introduced players to the gimmick for the first time. When the event originally started, the later stages of the event were not released till a day later in order to make sure the gimmick was working as intended. When the later portion of the events were introduced, players would be greeted with a surprise which would present a greater challenge for them once they reached E-7 Operation FS.

Operation FS introduced the Air Defense Princess, an abyssal air defense destroyer boss, which while was tough in general, was only made harder to defeat due to her incredibly high defense. The Devs tweeted later in that day that there was a system that players need to figure out to destroy the 'enemy's main defense" which would involve "destroying the enemy's supply line"

Players who managed to dig around would eventually find that key to weakening the Air Defense Princess would involve the following conditions to be met:

• S ranking Node X which had the Harbor Princess
• S ranking Node Y which had the Isolated Island Demon
• Taking out a large amount of enemy Transport Ship Wa-Class

If some of these conditions were met, this would result in the Air Defense Princess's defenses dropping enough to allow for your fleet to do significant damage to her. The effect was gradual and her defense would drop as the conditions were further met.

However, all armor reduction bonuses would be removed each day at 5:00 AM JST and players would have repeat to process to weaken her once again.

Fall 2015 Event - Western Front! Deploy a Mobile Task Force E-4

Submarine Princess after debuff takes full effect.

The Fall 2015 Event would be the second time in which the armor reduction mechanic would be introduced into the game. Unlike before hand where the effects would happen on a gradual basis, the mechanic would only activate when all conditions were met.

Players would have to fight against the Submarine Princess who was also given a high armor buff but could be weaken under the following conditions:

• Defeating the Harbor Princess at Node J
• Defeating the Anchorage Princess at Node M

Meeting these conditions would drastically reduce the Submarine Princess armor drastically and would result in a change in her dialogue and image. The image was however only available to those that used a mobile task force which players were encouraged to use since it would grant a higher accuracy bonus against fighting submarines.

Like before hand, the mechanic would reset after each day, but this time the time of reset was set for Midnight JST.

Fall 2015 Event - Survive! Vanilla Bay Night Battle! E-5

Destoyer Water Demon after debuff takes full effect.

Within the same Fall 2015 Event, players who made it to E-5 would fight against the Destroyer Water Demon who was given an armor buff of her own. Her requirement were different as she required the following conditions:

• Defeat a total of 15 PT Imp Groups during the attack phase of the operation.

As usual, when these conditions were met, a drastic change to her image and dialogue would take place. Most notable change was that she would lose her helmet when the debuffing process was completed.

Like before hand, the mechanic would reset after each day, but this time the time of reset was set for Midnight JST.

Spring 2016 Event - Operation Recapture Friendly Anchorage E-6

When all the requirements are met, it was quite possible to single handedly kill of the Central Princess in a single blow during the opening battles before the main fight began.

Unlike the previous events, Spring 2016 Event in E-6 introduced a complex but simple mechanic that was confirmed to be a multi-stage process debuff. On top of that, admirals were required to go through several stages in order to actually perform the armor reduction mechanic against the Central Princess.

In order to make the the Central Princess vunerable, admirals were required to do the following steps:

• Survive an air attack from node L on E-5 without taking any damage
• Score an S rank on Node A in E-6
• Score an S rank on Node G in E-6
• Score an S rank on Node L in E-6

Upon completing 2 out of the 4 steps, the Central Princess would being to experience a reduction to her armor, but the full effect would not take place until you had completed all 4 steps which would also result in a small change to the Central Princess's lines. In addition, the debuff was triggered only by attacks done by dive bombers and possibly Seaplane Bombers during the Aerial Phase and the Carrier Support Expedition in battle. As in most cases players were able to take out the Central Princess in a single blow before the battle even started.
