Conventional Logic

botted moss giants for ages trying to get row drops, obtained a dragonstone.

botted blue dragons for a while trying to get row drops, obtained a dragonstone.

botting dworges trying to get some row drops, obtained a dragonstone.

there are 25 new row drops.

in shit loads of botting various monsters, i have managed to access this drop table, 3 times. all 3 times, i obtained a uncut dragonstone.

out of all 25 items in the table, uncut dragonstone is the second WORST item at 56,000 gp, the worst being 200 adamant bolts, approximately 42,000 gp.

getting a uncut dragonstone once, 1/25 chance.
getting a uncut dragonstone twice, 1/625 chance.
getting a uncut dragonstone a third time, 1/15,625 chance.

I Am Fucking Immense :O

 

Thats not logic...

For starters, your assuming that all 25 drops have the same equal chance of dropping.

 

I'm pretty sure sapphires, emeralds and rubies (which are also on the rare drops table) are worth less than dragonstones.

You probably also got the drop a couple times and just didn't notice.

 

ill give you that. i am assuming all items in the ring of wealth drop table, have the same rarity of obtaining, but until further information is acquired, it is the general assumption.

rare drop table, is separate to the ring of wealth drop table, all gems lower than dragonstone are not included in the ring of wealth drop table. the lowest value drop is 200 adamant bolts, check the rswiki.

 

You're right that it's not a ring of wealth specific drop, looks like I over-read that part in your OP.

My bad.
