OSRS Vasa Nistirio Guide: Crystals, Gear & Mechanics

Vasa guide for crystal walking, gear, and consistent room clears.
Overview: Vasa Nistirio at a Glance
Vasa Nistirio is a full boss in the raid group, rated 3 out of 5 in our boss index and normally fought solo or team.
Before you can fight Vasa Nistirio you need Chambers of Xeric.
Crystal walking is what this fight actually asks of you, and it is the thing standing between you and raid points toward CoX uniques.
Its own attacks are magic and ranged, so Protect from Missiles and Magic both have a job.
In our index it sits in the raid group at difficulty 3 of 5, where kill times come down to crystal walking.
