Chilled question
Chill only affects CDs while it’s active, so for every 1 second of Chilled, the CD takes an extra 2 secs to tick. It doesn’t just directly change the numbers like your first question implies. Also, note that it is very strong against mobility too. Chilled+a bit of ‘AoE bait’ is a great way to force dodges to setup for a burst. Chilled will also slow down the Ele’s attunement recharges. Try to survive one ‘rotation’ until they leave water, then hit them with it and cover it asap. A DD Ele would probably rather have to deal with any other condition (or even a couple) in the game besides Chilled. It’s a huge pita for them. Access to it isn’t super common though so use it wisely. Hope this helps.
