[Infiltrate] allows [Ivara] to easily deal with annoying spy missions without having any knowledge of the mechanics or tile sets. Unfortunately Prowl forces [Ivara] to move at a snail's pace so we utilize a subsumed movement ability and high ability strength to counteract it.

Infested Mobility is chosen because it allows you to quickly get from vault to vault. It also increases your parkour speed which lets you roll quicker in flat vaults and bullet jump higher and farther in vertical vaults. Fire Walker and Molt also work but for different playstyles. Fire Walker is much slower but more controllable. Molt is much faster but has less duration.

Duration and Strength are pumped up to synergize with the movement speed bonus from [Infiltrate] and the duration on the subsumed abilities. It also lowers the energy drain during Prowl.

[Enemy Radar] helps you and your team to find enemies at an even greater distance. It may be overkill when combined with [Ivara]'s passive and [Animal Instinct] on companions when you are on smaller tile sets.

Arcane Agility significantly increases your movement between vaults but requires you to get hit or to abuse the [Combat Discipline] synergy. Arcane Consequence also works but requires to quickly head shot an enemy between vaults. Choose whichever one suits your playstyle.
