Forte Upgrade Materials for Cartethyia
Upgrading Cartethyia’s Forte abilities takes her to the next level in both damage output and utility. You’ll need a large quantity of Metallic Drip materials, Tidal Residuum, and the weekly boss drop When Irises Bloom.
Required Forte Materials (Per Tier):
| Tier | Inert | Reactive | Polarized | Heterized | Tidal Residuum (All Types) | When Irises Bloom |
|---|---|---|---|---|---|---|
| 1 | x5 | x5 | x8 | x11 | 4 x LF → FF | x4 |
| 2 | x10 | x10 | x16 | x22 | x10 each | x8 |
| 3 | x15 | x15 | x24 | x33 | x15 each | x12 |
| 4 | x20 | x20 | x32 | x44 | x20 each | x16 |
| 5 | x25 | x25 | x40 | x55 | x25 each | x20 |
By Tier 5, the farming burden is substantial. Prioritize the metallic drip types needed for your current node levels to avoid wasted resources.
