Arcanist - how many DoTs at once?

You can stack up to 7: Bio, Bio2, Miasma, Miasma2, Shadowflare, Aero, and Thunder.

Just as this says. It can be a big help sometimes when your DPS party members are having a rough time with something

Thats the Scholar. Arcanist can cross some additional like the warriors. No sence behind that but in theory it goes higher.

SCH and SMN lose Aero as an option, to a total of 6, plus job skills. Fracture, Venomous Bite, Phlebotomize, and other Disciple of War skills have no affinity for arcanist. You can use them with other DoW, but not a DoM.
