Notes

• Channeled Abilities will only have their initial cast be free. Energy drain works as normal.
• Toggleable abilities, such as  Pacify & Provoke or  Spectral Scream can trigger the Arcane during initial ability activation.
• Abilities that have no initial energy cost AND cost less than 3 modded energy per second will not proc nor drain the charges of the Arcane, such as  Mach Rush,  Pulverize, or  Parasitic Link.
• Stacks with  Inner Might, allowing for an effective fourth charge when both effects are active.
  • Likewise with Inner Might, Arcane Steadfast doesn't have any effect when casting Railjack abilities.
• Abilities that have had their cost negated by Arcane Steadfast will not be able to activate Arcane Steadfast again when cast. Thus, it is impossible to experience an extended chain of zero-cost ability casts refreshing the Arcane; there must be at least one non-negated ability cast in between each set of three negated abilities.
• When Arcane Steadfast is active, 3 orbs of energy will orbit the Warframe, decaying after each "charge" is used.
• As neither  Hildryn nor  Lavos use energy, this Arcane has no benefit for them.

Tips

• At max rank is expected to activate ~67% of the time after 5 casts and ~90% after 10 ability casts. By nature of negating the cost of abilities, the energy saved by this Arcane is amplified on builds with negative Ability Efficiency.
• Ths Arcane works best on warframes with spammable, low-cost abilities to activate the Arcane and use the charges for higher-cost abilities:
  •  Ash's  Blade Storm will not consume charges on initial activation or marking the target, however will consume one charge on ability de-activation and will refund all energy spent marking targets as  Blade Storm marks are consumed by clones.
  •  Atlas'  Landslide becomes more cost-efficient on successive casts and free with the  Rubble Heap augment, allowing the user to spend a low amount of energy to trigger charges and spend them on abilities such as  Petrify,  Rumblers, or subsumed Helminth abilities. For the cost of one cast of Rumblers, Landslide can be cast 12 times in a single combo chain, accruing a 93% chance of activating this Arcane.
  •  Styanax's  Axios Javelin costs 15 energy (at base) while his  Final Stand costs 100, so activating the arcane even after "unlucky" 10 casts for his Final Stand totals in 150 energy used instead of 300.
