i want ask if i use the jewel have "chilling presence" ,can it make the debuff ?
chilling presence is chilled ground right???
thanks for all of you~~~

Chilling Presence:
Nearby Enemies are Chilled.

This means every enemy who is "near" you (what "near" means requires a bit more delving in numbers, and knowledge of Units in order to have an exact measure). It does not mention any chilling area. You don't create a Chilling Area "nearby" you by having a Chilling Presence or a similiar modifier.

Chilling Areas, as suggested by the Enhanced Tooltip of Chance to Sap Enemies in Chilling Areas, are:
> Vortices from Vortex skill
> Creeping chilling areas from Arctic Breath skill
> Chilling Areas from Cold Snap skill
> Chilled Ground from skills like Arctic Armour (NOT Chilled ground from an enemy's skill or already on the map because of a Chilling modifier)
