The Great Rift Mechanics




Amplify Effect List

All Great Rift Round 2 Amplify Effect
・ Increase Damage Amount of Instinct and Order Cards by 50%
・ Increase Damage Amount of Exhaust cards by 20%
・ Gain Combat Score based on the Damage Amount, and once you reach a certain threshhold of damage, the score you receive in this manner will gradually be reduced.

Vanguard Mechanics - Tyrant's Outcry

A global mechanic of the Colossus are its breakable parts. After hitting multiple times, the Colossi will inflict harmful effects or perform an attack action.

Once both arms are destroyed, you'll be able to use a few number of attacks on its main body. You'll have 10 turns to defeat the Colossi on the Vanguard Phase and left over turns will carry over to the Rearguard team.

Rearguard Mechanics - Counterfeit

Similar to the first phase, you'll need to destroy both arms first to open up an attack opportunity to the main body. However, unlike the first phase, its second phase can only take a single hit. It has an infinite amount of HP so ensure that your last attack will be the highest damaging attack you can use.

What is The Great Rift

Two Teams and Two-Phase Boss Fight

The Great Rift

The Great Rift involves forming two teams to take on a two-phase boss fight. The goal of the event is to score as many points as you can within a limited number of turns. There will be obtainable effects during the fight, and the higher your points at the end, the higher your rewards can be!

It is imporant to note that there will also be cumulative rewards as you repeat the fights, but there will also be rewards based on the highest score you get.

Obtain Record Rewards Based on High Score

After dealing damage, the damage you deal will be converted to your run's score. Your score will determine the rewards you can get and weekly cumulative rewards will also progress based on the total score you get throughout the week.

Merit Ranking is the Leaderboard and Shows the Top Players

The Great Rift Leaderboards

A unique addition to this event would be leaderboards showing the top players in The Great Rift. You can use this to copy their strategies and further improve your scores! The ranking will display the top 1000 players and will have separate calculations for the first and second half of the season.
