Blight · Path of Exile: Gem levels and requirements

Using this reference

Choose the gem level for Blight before checking requirements or mana cost. Values from two different levels do not describe one usable gem. If you are planning an upgrade, compare the next level with the attributes and resources your character will have at that point.

The skill-type list records source tags. It helps you identify the kind of skill, but is not a complete test of support compatibility or a damage calculation. Check the linked skill documentation for interactions before committing to a setup.

Blight includes 20 recorded variants. Comparing Blight · 1 with Blight · 20 changes these fields: Gem level: 1 → 20, Required character level: 1 → 70, and Listed mana cost: 2 → 5.
