earliest level to do blighted bog?

[Archaven]

so my party of level 10 get decimated at blighted bog. the plague insects and the foul wave by bog ooze are really strong.

 

any best strategy at level 10 to take them out? i took out amira's roost at level 10 without problems though.

 

ps. i used antidote as well. anything to counter the foul wave? not only it hit a tonne of damage, it inflicts DOT. cast suppress doesn't seems to help either.
