Best 0-4 level combat itens?

Yea winged shoes are quite good wether you want it for strategic purpouses or to fly and attack rear on the battlefield.
About Crystal/slave Matrix you can use it to boost paths that are not native to you for example to get high death/blood/Air with Bandar log rudras.(Or any other commanders that have strong magics but you want to make them stronger turn 1) So i'd say they are quite useful. Situational but useful.
I agree about the Flambeau.
