Warrior's KD Gloves, how do they work?

Hey guys

Is there anyone that can confirm if the 'lengthens knockdown duration on foe' gets triggered by not only the Warrior's KD skills, but other skills like Meteor Shower as well? By how long is the KD duration increased?

Excerpt from the SoF website:
- Stoneskin Gauntlets raise all knockdown times under two seconds by one second. (CxE)
- Stonefist Gauntlets affect all forms of knockdown. This includes non-hammer knockdowns. (Teny)

Godly O.o

Can you provide a link to SoF please?

Stonefists lengthen the knockdown time of skills and spells by one second. However, for skills and spells that have a knockdown length of 3 seconds or greater, the effect is not applied. Examples of this can be seen with backbreaker and gale.
