Some commentary:

Int doesn't matter.

It's harder to improve assassinate the higher it gets.

Tougher opponents are, yes, somewhat more likely to yield an improvement than very weak ones. This isn't a huge factor but probably will feel like it has more weight the higher assassinate gets since it can get so hard to improve.

As a player I've gone streaks of 20-25+ without an improvement if it makes you feel any better.

...one, according to Jalim when we still talked outside of CF, he told me that a while back they changed assassinate. He didn't get improvements for like 20 straight assassinates. Now, the point of this, is I think that was a partial fix by the IMMs that finally went truly live and bug free about two months later. IE If you assassinate someone you recently assassinated (never a problem for you, but still) you won't see improvements.

Two, Nepenthe commented on Balrahd's death thread about how Ktaar had the greatest luck of all time with assassinate improvements.

And finally, Three, Vens (aka Shapa) is the most unlucky bastard ever. You think you were unlucky? Vens had roughly 100 assassinates and STILL NO 100% in the skill.

Feel a bit better?

Edited to add: You had 13 assassinates on Mizfara with a % of 88? Dude, you can't ever complain about bad luck since that's the craziest run of luck I've ever seen. Every single assassinate (assuming no skill-ups for various reasons) gave you an improvement!

>...one, according to Jalim when we still talked...

He said the same to me. But check out Lohoq and Xligro, both of whom were contemporary to Sivyh. That is to say "way after Jil".

Susubienko had the same number of assassinates and same final percentage, albeit with arial intelligence instead of felar. If intelligence matters.

Not sure why I didn't add him to the list. Probably because he was too old. Vens had 88 assassinates and ended up at 99%.

That's not too far off what Ramora and Deas experienced.

I just never posted his stuff.

Nanorab being the other (eewwwww, Yhorian).

gr

I might have had Mizfara's luck with the improvements because without looking, I think I actually mastered it at around 50 - the last 10 or so successes to my recollection were with assassinate at 100% (side note, assassinate is sick at 100%).

I read your and TMNS's posts on the way into work today, and thinking back, I wonder if I'm always extremely lucky the first time I play powercombos. It seems like things always lean my way in terms of success with these combos -- to the point where I'm absolutely convinced they're OP in some way and won't play them again out of lack of interest -- whereas I still can't make something like a high-PK elf ranger work (for example).
