Notes
- Though it is not mentioned in the description, this Arcane grants 1 Arcane Revive at max rank, similar to other Warframe Arcanes.
- At rank 3, while active, ammo is not consumed.
- Speculatively, ammo efficiency probably uses a similar calculation to Reload speed [citation needed]: Ammo Consumption = Ammo Cost per Shot ÷ (1 + Ammo Efficiency Bonus)
- For example,
Twin Kohmak, which cost 1.67 ammo per shot at full spool-up, and 100% ammo efficiency bonus would cost: 1.67 ÷ (1 + 100%) = 0.835 ammo per shot[citation needed]
