Physical Guardians might be an ok leveling strat / beginner build for Physical Oathkeeper
(this build or Octavius Warlord for example).
You can have 5 fully Physical Guardians with just target farmable items
https://www.grimtools.com/calc/lV701ayZ (conversion on off-hand
should be fine here with Fire being converted first by Elemental conversion)
and maybe add some component skill from blueprint that drops along the way.
I was playing Physical Aegis on Veteran but while leveling damage
on single target bosses is not quite there so I moved the points to Guardians
and with early conversion items such as Viper Sandspitter and Korvan Spaulders
(if leveling from scratch you go to Forgotten Gods after killing Warden I guess).
they deal enough damage. Later target farmable Beronath and Magi Visage.
