New Genesis: Photon Sensitive Effect
PSE (Photon Sensitive Effect) is a mechanic that only appears in Combat Sectors. It is represented by a meter that appears on the minimap which shows the current level of the PSE. The gauge has 5 segements, filling it to full activates a PSE Burst which allows you to kill large spawns of mobs around the location,earning large amounts of N-Meseta and drops.
PSE Gauge
To activate PSE Burst, you need to fill PSE Gauge, seen on the picture on the right. The gauge has 5 segments, and it will increase and decrease as you kill enemies. The chance to increase is always 10% for each enemy killed, the chance for decrease is 5% if you are killing the enemies around yellow E marker or that are Trial target, otherwise it is 10%. After increasing/decreasing there is a 5 second grace period where gauge will not increase or decrease. PSE Gauge affects spawns of enemies, increasing chance for enemies to spawn as Silvered/Golden or as Megalotix.
You can fill the gauge to 4 by normal means. To activate PSE Burst, you need to clear a Trial while gauge is at 4 to fill the last segment. However, if the final enemy of the trial happens to decrease the gauge, no PSE Burst will occur. The opposite effect applies as well - if the last enemy fills up the gauge, PSE Burst will occur.
There are things however that affect the gauge outside of that as well. Clearing a Chaos Trial increases the gauge by 1 at the clear/failure of the second trial, so long as one of them has been cleared. During Storm-type weather the gauge will be locked at 4.
There is a pity system as well. The game checks if the following 2 conditions have not occured within 5 min:
- The Room Host, the currently oldest person in the room to whom all enemies synchronize to, has not left,
- PSE Burst Climax has not occured.
If the conditions are met, the game will not decrease the PSE Gauge, allowing for easier time to get PSE Burst.
PSE Burst
When the gauge reaches 5/5, PSE Burst occurs. This will create a rainbow E marker at the spot where the last Trial was cleared. Around this spot, large amount of enemies will spawn with high chance of them being Rare/Megalotix. They will spawn up to a limit of 2000 enemies, should the limit be reached, no more enemies will spawn in. PSE Burst status lasts for 90 seconds (with exception of Neusen Plant which lasts 100 seconds).
There are some conditions however which will force PSE Burst even if Gauge is not 5/5:
- Completion of a Co-Op Trial with Aina and Manon
- Completion of "Radical Repossesion" Trial.
Should they happen, a PSE Burst will occur regardless of current gauge.
PSE Burst Climax
After timer for the burst runs to 0, a boss will spawn, which will be guaranteed to be Rare/Megalotix. Killing it ends the Burst,reverting the Gauge back to 0, unless PSE Burst Encore occurs. All other enemies that had not been killed after Climax Boss is killed will despawn shortly if they are not killed.
PSE Burst Encore
This mechanic activates with 20% probablity, once per Burst. Should an Encore occur, the entire PSE Burst is restarted with a new 90-100 second timer. The amount of enemies remains the same, so should you kill 700 enemies in the original burst, this means encore can only spawn 1300 more enemies assuming timer doesn't hit 0 beforehand. Once timer hits 0 again, Climax occurs as normal.
However, should PSE Gauge drop 3 times in any given room session, a PSE Encore Boost marker will appear near the gauge. This will double the odds of Encore of happening to 40%. This can be stacked once, should the Encore occur, the marker disappears and has to be regained.
PSE Burst ʄ (Forte)
A PSE Burst ʄ (Forte) is a rare variant of Burst, happening with 10% probability. This will ensure that all enemies spawn either as Golden or as Megalotix during the Burst. During Climax, a boss will also be either of the 2 forms.
Should Encore occur after a Forte, it will always be a PSE Burst Encore ʄ(Forte). However, a regular burst has if it rolls an Encore a 10% chance for it to be Encore Forte anyway.
