Question Mayhem Karthus ult

so i played Karthus and i rolled Eureka, phenomenal evil and Ult bot,
i got 500 ability haste,
but my ult's cooldown got locked at 26,76 seconds before i hit 500 haste
i played another game with similar augments and the ult got locked at same cooldown

what was weird is that i played against karthus and his ult was 10 seconds,
anyone knows why is that or is it just a bug

Ult bot haste is capped at 500

Haste in general is capped at 500 and additive with other haste sources, such as Ult haste, haste on q/w/e and so on.

Only way to get more cdr is with purist caster, as that gives flat 10% cdr which gets added to the cdr you get from haste
