My current budget is roughly 500ex, you can get similar results on 400ex.
I league started this build, the progression curb was very smooth.

Day 1 - Just arakaalis fang scion and some junk filler rare gear.
week 1 - low life scion, aegis aurora, decently tanky. (sim 30 viable)
week 2 - CI aegis aurora, very tanky, not a major change from the low life version. (I have some videos on my channel of this version)
week 3 - I took a break
week 4 - I sold all of my gear, and started from scratch doing a switch to the life based squire version with a mageblood. Overall I am happy with this change.

What made me want to try scion?
I challenged myself at league start to play a summoner scion. It was for fun.

Why do I prefer scion over occultist?
scion is tankier, while staying similar in single target dps. lowesr clear speed because no profane bloom though. Scion has a LOT of different build options that occultist doesnt have access to such as the low life version with covenant chest piece and coruscating elixir.

Would I recommend this build?
Only if you have the willingness to self craft all of your gear, and can be creative with the progression curb. This is not a build for the feint of heart or inexperienced player.
