Surprisingly not a thread begging for a drop rate increase, though I'm sure we'll get to that.
So powers that be,
Please let us trade 100 Alexandrite to Ghanraam (or any NPC really) to obtain something like a Shining Alexandrite, worth 100 Alexandrite for Duties, Tasks and Deeds, that stacks to 99 itself and can be traded/bazaared.
Call it a wavering resolve to finish the quest, but I don't want to commit any Alexandrite to a weapon until I have all 30,000 of it - considering it is a 240m~360m investment - which as it stands will take up 304 inventory space and I don't think I need to say how bloody ridiculous that is, but I will anyway:
Needing 304 inventory spaces for 30,000 Alexandrite is bloody ridiculous!
Having what would effectively be a 100 Alexandrite item that stacks to 99 would take that down to 4~5 inventory spaces which is similar to the amount of space taken up by currency for upgrading a Relic weapon. Considering last Bonanza added a Cat's Eye that effectively counted as 30,000 Alexandrite for the quest I know it's perfectly possible to make this adjustment.
Inventory space is probably the biggest issue I have with Duties, Tasks and Deeds at the moment, though that doesn't really mean much when Duties, Tasks and Deeds is basically one big ridiculous issue to begin with, but I'll save that for for when I'm less annoyed at contemplating how to easily free up 304 inventory spaces. I don't know who originally came up with the player logistics of this quest, but I do hope you fired them - or even worse, sent them over to FFXIV.
