Familiar Drop Multiplier

Now, I know that familiars give a certain rate of drop increase, but how do we find out whether if its 1.6x or more?

I mean, it's common knowledge that Big Spider or Mutant Pig gives a 1.6x increase, and the Wolf Underling gives a 2x increase.

Is there any other familiar that gives 2x increase? or does anyone know if Castellan is 1.6x or 2x?

Thanks in advance

Castellan is 1.6x. I have no idea if any other 2x ones exist. I think WU might be the only one.

Without getting into all the data stuff, you can pretty much tell the bonus by the description (the descriptions are linked to their effects, after all).

Items OR Mesos
"Increases the [item or meso] drop rate by a small amount while summoned." - +30% Drop Rate for Items OR Mesos
"Increases the [item or meso] drop rate while summoned." - +50% Drop Rate for Items OR Mesos
"Increases the [item or meso] drop rate while in [Certain Area]." - +50% Drop Rate for Items OR Mesos in [Certain Area].
"Increases the [item or meso] drop rate by a large amount while summoned." - +100% Drop Rate for Items OR Mesos (Wolf Underling Familiar is this, and it's the only one for item drop).

Items AND Mesos
"Increases the drop rate of mesos and items by a small amount while summoned." - +20% Drop Rate for Items AND Mesos
"Increases the drop rate of mesos and items while summoned." - +40% Drop Rate for Items AND Mesos (Ergoth Familiar is this)
"Increases the drop rate of mesos and items while in [Certain Area]." - +40% Drop Rate for Items AND Mesos in [Certain Area]
"Increases the drop rate of mesos and items by a large amount while summoned." - +60% Drop Rate for Items AND Mesos (Big Spider, Mutant Pig, Toad (Castellan) are this)

Ah, thanks, much appreciated.

I suppose B> WU Familiar in Broa now
