Noblesse Skills

Harmony of Noblesse - This Noblesse skill combines the energy of 4 individual Wizards (Sorcerer, Spellsinger, and Spellhowler). The energy of each individual must be received consecutively in intervals of 5 seconds or less regardless of type or order, and the skill must be used within 5 seconds of receiving the energy of the 4th individual. It is a non-elemental magic attack with twice the potency of Elemental Assault.

Symphony of Noblesse - This Noblesse skill combines the energy of 8 individual Wizards (Sorcerer, Spellsinger, and Spellhowler).

Has anyone had successful results with these two skills? What were the successful conditions. We tried last night, I hit a B grader for 1 dmg, and a hero and an archer for 1 dmg. Is there a condition I am missing?

there is a post exactly like this somewhere
and no ive never used em, something about being buffed by a bunch of mages so a dorf can cast a spell just makes me sick

they're useless.

dmg is still baised on m atk, so the only classes worth doing it are sorcs/necros and SH's
