Vortex + Bonechill, how is it going to work?

Vortex chills the enemy standing in it. Bonechill 3.15 has "44% increased effect of chill on enemies" AND "enemies chilled by supported skills increase Cold Damage Taken by Chill effect".

Questions:

How strong is the resulting chill effect?
How much increased cold damage (from any sources) will the enemy be taking while standing in this vortex?

Answer:

The enemy in this case isn't being chilled by Vortex, but by the chilling area (ground effect) it creates. Thus the relevant stat on Bonechill for this is the other one: "Enemies in Chilling Areas from Supported Skills increase Cold Damage taken by Chill Effect". But the support always has both stats, so that doesn't really change the answer.

The chilling area has the default chill magnitude of 10% reduced action speed. This is scaled by the 44% increase from bonechill and any other modifiers to the effect of chill (or chilled ground) your character has to determine the final magnitude (to a maximum of 30%). With 44% increased effect from Bonechill and no other relevant effect modifiers, the chilling area will have a magnitude of 14% reduced action speed.

While the enemy is in the chilling area, they increase cold damage they take by the same amount chill is reducing their action speed. So if the chilling area from Vortex is reducing their action speed by 14%, they will take 14% increased cold damage.

However, if they have a stronger chill on them, that chill will apply it's higher magnitude instead of the chilling area, and as long as they are in the chilling area, they increase cold damage they take by the magnitude of chill applying to them. So if they also got hit by cold damage that inflicted a chill with the maximum magnitude of 30% reduced action speed, that's how much they'll be increasing cold damage taken by.
