Noob crafter looking for help on crafting caustic arrow bow

Hello I want to craft an end game bow for my chaos build and looking at poe ninja I noticed almost everyone has the same bow, which makes me think there must be a way to craft it

here's the bow in question:



I already have a hunter maraketh bow atm, how would I achieve similar results?

Here's a video Path of Matth made a few weeks ago regarding crafting a +3 bow for toxic rain/caustic arrow. He uses thicket bows in his video, but for CA maraketh is perhaps preferred due to move speed bonus. He does two variations; the first is best for what you want for CA.

There is also a web based tool you can use to practice called Craft of Exile; https://www.craftofexile.com/

Do make sure that your bow is ilvl 82 and is already 6-linked prior to starting the actual craft.

awesome thank you =)
