How many was the most times you ever grinded an instance for a single specific item?

[Laurima]

WoD

Before Heavensward

Demon healer robes,

50+ runs

1 drop, ninja'd by a useless healer with dreadwyrm robes on ><
(I had 100 SOL robes)

[Jamillion]

I don't keep count, though for gearing up all of my 50s I ran ST a couple hundred times after the lock was removed

[Rhaja]

Two days of about 5 to 6 hours a day in Sohm Al to get my fiance a Gaelikitten. The victorious cry was fierce the night it dropped. The squee of joy when she came home from a rough day of work and saw it in trade made it worth it.

[Arielyanna]

I ran Garuda Extreme 399 times til I got Xanthos (Primal Horse Mount)... the run immediately after that, I finally got the Nightmare mount.

[RyuSaarva]

I beat leviathan X about 120 times before I saw a pony drop for the first time and I also won it, I did not see any other pony drop before droprate nerfs.

[Velox]

I did run #41 two nights ago of t9 for the High Allagan Crook. It still hasn't dropped.

[Leowilde]

Probably 5 or 6.
A while back for a primal weapon.

[Werhusky]

Leviathan EX for the axe. First drop at about 150 runs, got it like 10 runs after.
Still missing out on the High Allegan Blade I am on about 100 clears pre HW/after HW and seen it drop once.

75 kills in turn 12 for my BLM body piece. Drove me insane.

If you really farm T12 for BLM body you will farm forever.. it's T11

[Synrin]

Ran The Lost City of Amdapor cca 30 times, still no Darklight Gloves of Healing..

[Stormfur]

Ramuh Ex about 100 times for the DRG weapon. Lost City of Amdapor what feels like 1,000 times for the Darklight set for Monk and DRG.
