Rune stats and forge upgrades
Every stat has a base value. Each star above the first adds 33% of that base, and each forge level above 1 adds 6% of the starred value. The result is rounded to one decimal.
The rule
value = base x (1 + 0.33 x (stars - 1)) x (1 + 0.06 x (forge level - 1))
The forge takes a rune up to level 12. Each level raises the main stat.
At levels 3, 6, 9, 12, each extra stat goes up one step too, and the forge adds one new extra stat while the rune has fewer than 6.
A new rune starts with a number of extra stats set by its rarity: Common 0, Uncommon 1, Rare 2, Mythical 3, Heroic 4 (not obtainable in this game version), Ancient 5 (not obtainable in this game version).
Example: Poison Damage

| 1 | 12 | 19.9 |
