Creation(330) vs Crafted PLD weapon and shield

[aleph_null]

It always depends on how close you're to clearing last floor. If you'll clear o4s soon then the tomestone weapon is somewhat a waste of tomestones, but if you won't clear o4s soon, it's a good investment to help your group through the progression. Not everyone is good enough to clear o4s in full 320 gear, so every bit of dps counts. It's more cost efficient to hold out until you get the i345 weapon by skipping the tomestone weapon, but if everyone does the same you might struggle with dps checks and take longer before you clear o4s. That said, the difference between pentamelded i320 weapon and i330 is quite small.

Have you cleared o3s? Will you be getting the upgrade item (roborant) soon? If you're currently progressing in neo exdeath and close the latter parts of the fight, then you should hold out and not spend your tomestones on the weapon. If you just started o4s or still progressing in o3s I'd say it's worth investing on the tomestone weapon
