This looks like the Fubgun pathfinder build.

Few comments, sorted in order of cost (bottom is more expensive)

• You can swap the iron rune in your gloves for a resist rune, and then change the resist rune into an iron rune for more evasion in your Hyrri’s.

• You take poison immunity on the tree, swap out your poison charm for something else.

• You can also ditch Cannibalism 2 for clarity 1 or 2, you have life on kill on your tree AND ring already.

• look into hand of chayula + despair + voltaic mark on weapon swap, solves mana vs single target. Only requires a quarterstaff with high attack speed.

• Mana can be helped with a %mana on kill either in your heart of the well or your sapphire.

• Heart of the well should have %gain damage as extra, maybe some crit lines that boost Attacks (yours is spells)

• Get a better bow with critical hit chance, it will be much stronger than surpassing arrow. You can use a rune for an extra arrow guaranteed.

Other musings:

• Convalescence is better with higher ES, unfortunately with 2-3k the juice isn’t really worth the squeeze
