Tier 2 upgrade table
Sigil Essence + Rune Recipe
Tier 2 uses its own compounding formula: Sigil Essence + Runes. Sigil Essence is a Tier 2 upgrade material, while Sigil roll skill is still an open source skill in the pool. The lowest rune starts at Vex, because Tier 2 is the endgame branch after players have invested in Tier 1.
| Level Tier 2 | Sigil Essence | Runes combined | Total Sigil Essence | Note |
|---|---|---|---|---|
| Lv1 | 0 | - | 0 | Open Tier 2 after unlock conditions |
| Lv2 | 5 | Vex Runes | 5 | Startup phase |
| Lv3 | 5 | Vex Runes | 10 | Startup phase |
| Lv4 | 5 | Vex Runes | 15 | Startup phase |
| Lv5 | 5 | Vex Runes | 20 | Startup phase |
| Lv6 | 8 | Ohm rune | 28 | Stable phase |
| Lv7 | 8 | Ohm rune | 36 | Stable phase |
| Lv8 | 8 | Ohm rune | 44 | Stable phase |
| Lv9 | 8 | Ohm rune | 52 | Stable phase |
| Lv10 | 8 | Ohm rune | 60 | Stable phase |
| Lv11 | 12 | Lo Rune + Sur Rune | 72 | Endgame phase |
| Lv12 | 12 | Lo Rune + Sur Rune | 84 | Endgame phase |
| Lv13 | 12 | Lo Rune + Sur Rune | 96 | Endgame phase |
| Lv14 | 12 | Lo Rune + Sur Rune | 108 | Endgame phase |
| Lv15 | 12 | Lo Rune + Sur Rune | 120 | Endgame phase |
| Lv16 | 18 | Ber Rune + Jah Rune | 138 | Completion phase |
| Lv17 | 18 | Ber Rune + Jah Rune | 156 | Completion phase |
| Lv18 | 18 | Ber Rune + Jah Rune | 174 | Completion phase |
| Lv19 | 18 | Ber Rune + Jah Rune | 192 | Completion phase |
| Lv20 | 30 | Ber Rune + Jah Rune + Cham Rune | 222 | Max Tier 2 |
The total to reach Lv20 is 222 Sigil Essence with high runes from Vex and above: Vex at the beginning, Ohm in the middle, Lo/Sur from Lv11, Ber/Jah at Lv16-Lv19 and Ber/Jah/Cham for the final level. This method keeps Tier 2 different from Tier 1 but is still more expensive, true to endgame quality.
