A New Bug of Barber & Manitou

When I wear the new Barber and Gazing Demise, use the Spirit Barrage to attack a single enemy three times, then wait a minute.

Manitou Rune:

  1. When the SB of Manitou don’t attact that enemy
    After 10s, The damage from Phantasms will explode three times in a row.
    After 20s, the damage from SB of Manitou will come out.

  2. When the SB of Manitou attact that enemy
    After 10s, The damage from Phantasms will explode only twice in a row.
    After 20s, the damage from SB of Manitou will come out. (Damage value is the same as before)

Other Rune:
No matter whether the Spirit Barrage attact that enemy, after 10s, the damage from Phantasms will explode three times in a row.

OR

If I use the Spirit Barrage to attack the enemy or the space another three times, no matter whether Runes, the damage from Phantasms will explode three times in a row.

Which means one of the damage of Phantasms has been offset by the attack of Manitou in the above situation.
