Drop rate question

Helll guys
I wanna ask about drop rate
So, if i just want to farm material from monsters, i dont need any equipments and xtal, just the mats only
Example is lavarca drop table here:

Do i need LUK or not?
Will adding LUK will cause more equips and xtal dropped thus making it more hard to farm if i only want the materials?
Anyone here could share some info regarding this?
Thank you

 

there is no limit on the number of drops per kill. in theory you could get everything on the list at once.
each item drops at a specific probability. drop rate boosting effects raise the drop rate of all items, you cannot make a single item more common and decrease the chances of getting other items.

in most cases, the base drop rates of regular items is 50/25/5%, with rare items (crysta and gear) being 5% and less.
