Just out of curiosity I made a tally (is this the right word?), a list of droppings per killing Renowned.
According to my experience I get a 'drop' averagely every 50 kill/corpse. This is just any arti, may not be the desired one.
I was lucky with the Tinker legs, which came around 50, shortly after another arti. But for this silly Basilisk Breastplate I killed over 200 Tikitavis, together with about 50-60 other Cavern Bosses I killed just out of boredom - and annoyance. Got 7 arties in that time alltogether but from Tikitavi between the second last and last drop over 100 blank!
Edit:
I hate to edit my posts but I hate even more to be inaccurate.
So just FYI (only the example Cavern of the Discarded, disired item: Breastplate)
- Fastest drop: 13 (two in the 20s)
- Latest drop: ca. 120 (sorry but I quit counting after number 100), Tikitavi, Basilisk Breastplate, Drop-Nr. after all: ca. 240
(From Tikitavi: Breastplate, Legacy of Despair (2), Mystic Garb (2) / From Vitavi: Demon Bridle Ring, Void Infused Kilt)
so in total: (did not loot every corpse)
- 7 artis; (Drop rate only Tikitavi: ca. 240 / 5 = 48)
- 732 Essence of Ballance
- ca. 180 (of each) Crystaline Blackrock, Crushed Glass, Crystal Shard, Abyssal Cloth, Arcanic Rune Stone, Loadstone, Elven Fletching, Delicate Scales, Powdered Iron, Seed of Renewal
- some Reflective Wolf Eye
- some Gold (not enough for the time spent but I guess the Imbuing stuff is worth some coin)
