One aura at a time
An aura multiplies Chakra. Only the equipped aura applies. Trophy auras are bought in order from the Auras menu. The aura catalog has every multiplier and cost.
Trophy line, short version
Spark is the first buy at x1.5 for 50 Trophies. The line then climbs through Blue Flame, Leaf Storm, Thunder, Sakura Storm, Astral, Amaterasu, Void, Celestial, Moonlight, Lotus Bloom, Starfall, Heavenly, Blood Moon, Demon Flame, Crimson Eclipse, Frostbite, and Abyssal Tide at x53 for 10No Trophies. Costs jump sharply after Thunder (x4 for 40K).
Other aura sources
- Daily reward track: Crimson Storm, Emerald Storm, Violet Storm, and Shadow Storm, one per week, each x3.
- Robux passes: Golden Sage x15 (R$149), Kurama Chakra x25 (R$399, Kyubi Chakra Aura pass), Otsutsuki x40 (R$899), VIP Aura x20 (R$199).
- Scaling passes: Susanoo Flame is listed at x6 for R$499 and "always 50% better than your best aura in every world." Rainbow Chakra is listed at x10 for R$1199 and "always 150% better than your best aura." Buy a strong Trophy aura before either scaling pass so the percentage has a high base. The card shows both a flat multiplier and a percentage; if the shop text differs, follow the shop.
VIP also lists x1.5 Chakra, x1.5 Trophies, and faster running.
Eyes or auras
Both spend Trophies and both multiply Chakra. Compare the next eye button with the next aura button. Take the larger multiplier gain for the Trophies it costs. Robux auras are a shortcut, not a requirement. The Trophy line and the weekly Storm auras are the free path.
