Drooping Darkness Jet

Introduction

• Jet is 1 of 3 Followers in Black Purgatory dungeon.
• You will face Jet if you take Destroyed Village or Dark Knight routes, you may find him in APC rescue if he intrude.
• Type: Demon

Divided Darkness Pattern

• Jet summon his clone that casts similar patterns as him.
• The clone is not too bad, it will disappear when the progress bar fill up.
• If its pattern and Jet's pattern overlap, the clone will disappear.

Darkness Release Pattern

• Jet jumps to the middle and starts releasing rays after rays of dark energies.
• This pattern can be messy if you get caught in the middle.
• Luckily, Jet marks on the ground first before the patterns start. You can avoid it easily by stepping out of the way.

Trap & Rescue Pattern

• Jet traps all but one member. He then spawns spikes damaging the trapped members.
• Non-trapped member will have a violet circle below him/her.
• Your job is to rescue by standing on them for a period of time.
• Successfully rescue all members will generate groggy.

Dark Meteor Pattern

• Pretty simple pattern. Jet jumps and do room wide AoE attack.
• You can dodge by standing in the lighted up green area.

Main Groggy Pattern

• This pattern activates when HP drops below 40%, and is very similar to Play Ball pattern from the Slime Twin from Sirocco raid.
• Jet jumps to the middle and surround himself with a big purple circle. 
• There will be another small purple circle spawned randomly in the map. You will also see one red line connect to this small circle.
• This line is the fly route of Jet's clone. Your job is to create and redirect his path so that the clone collide with Jet.
• To do this, player 1 need to step on the small circle AND stay there. Once stepped in, another red line will connect to another random player 2. And player 2 need to make sure this new red line go pass Jet.
• NOTE: Player 1 MUST counter jet as he's flying toward you (example below).
• NOTE 2: Sometimes the 1st line can cross Jet. However, that line doesn't count. Only the 2nd red line can create groggy.

• Here's another example, the clone flew across the top, then to the bottom diagonally.

Strategy

• Trap pattern is pretty much the only groggy before the main one.
• I would highly recommend you 1A and deal as much damage as possible to get to main groggy pattern.
• You should have plenty of time to line up the path, then finish him off.
