PLD Sortie Advice

Hello All,
Started running Sortie on PLD looking for any advice if possible.
Right now I have been full timing Sakpatas Sword and Aegis are any other shields useful on bosses?
I am also locking in SIRD gear during boss fights should I be in SIRD gear all boss fights and pretty much just there for the cures and to tank and not worry about dmg?
Thanks for any tips or tricks.

SIRD is going to do veeery little for most sortie bosses. Most bosses have magical melee hits, and magic hits don't interrupt spellcasting.

Degei/Aita/Skomora/Triboulex/Aminon are 100% magical melee attacks. No need for SIRD.

Ghatjot/Dhartok/Leshon/Gartel have one physical melee hit. And of those I'd really only have any concern about Leshon/Gartel maybe interrupting.

holycircle/Sepulcher C/G boss. use fealty on G. I actively try to do DPS on all bosses, everybit helps.


I use stage 3 duban/burtgang, and use exca/aegis on Aminon
