Question about Time Crawl

I made a Time/Fire Defender and I was wondering whether you can stack Time Crawl's -recharge to really neuter an annoying boss or such, so I crafted a Power Analyzer to see what stacked and what didn't on it. From what I saw, nothing about Time Crawl stacks if you apply it twice to the same target... not the recharge debuff, not rhe -regen, not even the movement slow. Is this true or am I misreading things? And is that true of slows in general? (I rarely play sets with powerful slows so I've never really paid attention.)

Nothing from Time's Crawl is set to allow for stacking from the same caster.

This in general is true of not only slows but also most debuffs in the game. Though any power that summons a pseudo pet gets around that by each pet being a different caster.

Generally speaking, debuffs from buff/debuff sets don't stack, while debuffs from blast sets do. If you have mids, you can check this by hovering over the effect and seeing if the popup includes a tag of "Effect does not stack from same caster".

Thanks... I usually don't play primary debuffers so I didn't realize that none of the effects would stack on them. I tend to think of slows as control powers so I just assumed it would stack like stuns or holds. Ah well, it looks like Distortion Field and Time Crawl will be enough to put a major dent in enemy recharge even without stacking, plus pretty much floor their movement. Now the only question is, stay Time/Fire for the damage or reroll as Time/Ice just to see how slow I actually can make things.
