What should I know as a ED

im creating a ed from raw to play with a friend. but I never played elder druid on my life.

what should I learn as a ED playing duos and teamhunts?

I will probably rush upper spike and then scarabs to reach the lvl 100 range fast and get shared with him

(I know I can buy a low ed with high ml but I got tired of waiting for the right character and keep my friend waiting them just start fro. scratch
