  • Despite the skill description, this Well pulses 4 times, with the first pulse applying on Well placement.
    • The first 3 pulses each deal the listed damage and apply chill.
    • The last pulse applies the daze and removes boons (and activates All's Well That Ends Well if you have it traited).
While it has the same listed cast time as  Well of Action.png Well of Action, it is actually one server tick shorter (40 ms).
