## Acquisition

Obtainable from the Arbitrations vendor in the Arbiters of Hexis room in Relays for 30 .

## Notes

• The bonus only applies to the Starting Energy of a Warframe when entering a mission and respawning/reviving from death.
• Starting Energy = Initial Energy + (5 × Free Mod Capacity) + (Total Energy × Mod Multiplier)
• Example: A rank 30 equipped with has a Total Energy pool of 850 and a preset Initial Energy of 150. Let's say she has 9 Free (or available) Mod Capacity. When equipped with a rank 4 Preparation mod (+45%, or x0.45), the Warframe will have 150 + (5 * 9) + (850 * 0.45) = 577.5 Starting Energy.
• Example 2: The same setup but with a rank 8 Preparation mod (+82%, or x0.82), the Warframe will have 150 + (5 * 9) + (850 * 0.82) = 892 Starting Energy. In this example, the surplus is effectively lost as it surpasses the 850 Max Energy cap.
• As per the second example, higher ranks of this mod are redundant.
• Between rank 4 and rank 6 of this mod, the increase seems to be around 9.5% instead of the linear 9% from other ranks. This makes a rank 5 Preparation actually grant a 54.5% bonus from Total Energy.
• This is because the max effect of this mod (100% of energy capacity filled) is not evenly divisible by 11 mod ranks. Mods do not display values in the decimal places.
• As already spawns into missions with 100% starting energy because of his Passive, he has no need for this mod.
• Does not work on Arenas (Index, Rathuum), not even when re-spawning after death.
• Falling out of bounds and reappearing does not count as spawning for the purposes of this mod.

## Tips

• It's recommended at lower-than-max rank on Warframes with high Energy capacity and average Initial Energy.
• The bonus can apply to Sevagoth's Exalted Shadow each time he is summoned.
• If equipped on your Warframe the mod will apply to your Archwing's initial energy during Archwing missions.
