Tower of Fantasy Ruby advancement
You can advance Tower of Fantasy weapons by using their corresponding fusion cores, which you get by collecting more than one copy of a character. After you get your first copy of Ruby and Sparky, you can purchase another copy through the limited store during her banner for 120 flame gold. Alternatively, you can get a duplicate of Ruby by pulling on the banner, but, of course, this is entirely up to RNG.
Advancing your weapons by spending fusion cores and gold unlocks special bonuses. Here are all of the bonuses you gain from unlocking each of Ruby’s advancement stars.
- One star: Emblazen boosts the damage of Spark Attack to 80%. Weapon skill cooldown reduces to 24 seconds

What’s the best Tower of Fantasy Ruby matrix set?
As is the case with other Tower of Fantasy SR and SSR characters, Ruby has her own matrices. This is the best set for her in most situations, due to its dramatic buff to her flame damage, and its useful shielding. Alternatively, combining two pieces of Samir’s set with two pieces of Shiro’s set is great for boosting Sparky’s damage and shatter even further.
The best SR option for Ruby has to be Sobek’s Swamp Shadow, which is great against large groups of enemies, like those in the Bygone Phantasm. For more information on the different sets available, check out our Tower of Fantasy matrices guide.
| ToF matrix set | Rarity | Effect |
