While we're at it, some other miscellaneous data about how status ailments work:
-All statuses have about a 10% random variance, just like Attacks and spellcards (eg Wriggle's Comet on Earth can inflict between 36000-44000 PSN).
-If you get inflicted by a status, your resistance reduces its initial duration by 5% for every 10 points of resistance (eg if you have 100 resistance, Wriggle's Comet on Earth would inflict between 18000-22000 PSN).
-The rate at which a status effect ticks down depends on your resistance, at 0 its 1 ATB for 1 point of status (so a 40000 PSN would last 40000 ATB), the recovery rate increases by 15% for every 10 points of resistance (so 50 resistance means 1 ATB equals 1.75 points of status, at 100 it would be 2.5 and at 200 it would be 4). As such, a 20000 status is effectively a 5000 status for an enemy with 200 resistance to that ailment.
Reisen's resistance reducing skills do not affect the recovery speed of the enemies (which probably means it doesn't passively reduce enemy resistance, but rather give your allies resistance piercing on their attacks).
-PSN deals damage according to how much ATB the enemy gains when under the status (ie it doesn't depend on the tick down of the status itself). PSN deals 1% of an enemies' HP for every 100 ATB they gain (so gaining a full 10000 ATB bar is enough to reduce them to 1 HP); PSN damage is reduced on bosses down to 0,06% HP per 100 ATB (or 6% for every 10000 ATB), Tokiko's Crossed Over Endangered Bird increases this by about 10% (ie about 6,6% per 10000 ATB).
-Status effects from multiple attacks do not stack, the one that's stronger remains. For example, if an enemy is inflicted by a 20000 PSN and you then inflict a 40000 PSN on it, the enemy will end up with a PSN effect between 36000-44000, straight up overwriting the original status effect; if in the same situation you inflict a 10000 PSN, the original 20000 PSN will remain. The only exception to this rule is Sakuya's Private Square, which will always overwrite whatever PAR the enemy already has (ie a 8000 PAR will go down to 2800).
