March Sets
Terpsichore sets assume Twashtar offhand. Twashtar sets assume Thokcha offhand.
If you have March and Haste, you should have Saber Dance up, I don't see why you would need or want to waltz anything at that point.
Ideal set.
Comments on varying ammo:
Twashtar: Hagneia
/SAM Twashtar: Potestas or Charis
Terpsichore: Hagneia
Not made of unobtanium set.
