How do chanters use ToT?

[SoekiWiz]

ToT lands on targets that have a "mana pool"

Hypothetically, you cast on a mob that has 1 mana left, you still get the full tap into your own pool.

Without clicking the video link, is this greater war boned skel in HS?

If it's a HS mob, they HT. As such, they're flagged as SK's and just don't have any spells loaded into their arsenal. SK = Manapool = Successful ToT

Hope that helps.
