I gained Mystical Meal and Weapon Recharging through Metamorphosis.

Whenever Soul Eater triggers on-eat, it will trigger Mystical Meal and Energizing Meal, which again will trigger Weapon Recharging.

Main Wands:

Staff of Frost and Wand of Corruption to keep opponents at a distance.

Weapons:

Unstable Whip and Projecting Glaive to trigger Soul Eater without letting opponents getting near me.

Artifacts:

Alchemist’s Toolkit, Unstable Spellbook, Talisman of Foresight, Timekeeper’s Hourglass

Ring of Wealth +4 and +2 helped me getting there.
