how to defeat heinkel the knight

the recommended level is 35, and preferably you have summoner asterix with deus ex and 2 support characters and 2 attackers

to help you more on defeating Heinkel here is the job setup i did

Yew : main job fencer and sub job bishop with spellcraft
Magnolia : main job fencer and sub job bishop with spellcraft
Edea : main job hawkeye and sub job summoner
Tiz : main job hawkeye and sub job summoner

here's main strategy you need to do

first use stalwart aurocs on Yew and Magnolia
after that just default until you get 3 points and for tiz and edea just  brave x4 immediately and spam [deus ex-blast] x4 and eliminate all the underling because they can pose a serious threat if not eliminated quickly

i will just add that get Yew and Magnolia p-def as high as possible because they are the one that is going to make the party survive

after you get 3 points for brave just heal and stuff but you can also do [blessing mist], and why do that? because your attackers will get one shot a lot and its better to just have auto revive rather than reviving manually

rinse and repeat
