Kill or Ignore The Tissuer?

[Songbottom]

Later on there's an optional boss called The Tissuer that makes a certain main boss easier if you defeat them. I chose not to and can't tell if there's any benefit gained for taking on the extra challenge, does anyone else know?

[Kashra Fall]

Don't know if there is a benefit for it, but if you ignore it, then Sirene will randomly get 4 shields after your turns.

Think you maybe need the picto he drop in the Bossfight vs. Sirene.
The Shields he give to Sirene are no problem.
Try it.

I dont know if there is a story option for why you should leave the tissuer alone but maelle and monopoly are monsters on shielded enemies. Maelle can strip all shield instantly and monoco can grab an ability fairly early which lets him bypass shields and do more damage to enemies based on how many shields they have. I've deleted 50% of a bosses health with ability alone.

Does anybody know if there are any benefits of keeping this non hostile (white?) Nevron alive?
I keep it alive for now. It's not missable and it's still there after killing the main boss.

[Summoner]

This is only for the Nevrons that have side quests. This one doesn't not affect that. The thing that makes the boss fight easier is the Pictos you get so if you got that make sure everyone has it in their Lumina for the fight.

I left it alive the entire game just to see if I got anything for doing it. it doesn't affect anything feel free to kill the sewing nevron.

[POMPOKO]

It drops a picto that helps you with the siren fight. And I haven't found any benefit on keeping him alive. the picto is against charm
