Greetings!

Here's my [Mirage] build for Void Fissures and speeding through regular star chart.
This build shares polarities with my setup for Sanctuary Onslaught, hence the 5 capacity left.

Requirements

• Arbitration (Preparation)
• (Optional) Helminth

Purpose of this build
This build aims for speed and efficiency in regular star chart - it does not scale into SP levels and beyond.
In my opinion, it does better than a Thermal Sunder Titania against armored threat in axi/requiem/lich missions, and is still quite fast and fun.

Abilities
You can acquire [Mirage] parts during the Hidden Messages quest.
[Mirage] passively slides 85% and has a 50% bonus to maneuver speed.

Hall of Mirrors (1) summons mirror images of [Mirage] that are invulnerable to damage, draw enemy attention and replicates [Mirage]'s actions. They deal a certain %tage of weapon's total damage.
[Mirage] is squishy, even for regular star chart standard. Enemies missing their shot is a plus! Also increase the damage you deal with your loadout.

Infested Mobility (2 - Infused through Helminth) grants parkour and sprint speed.

Eclipse (3) grants an adaptative bonus based on environmental lighting. While bathed in light, it increases weapon damage by up to 200% (increased by ability str), or reduces incoming damage by up to 75% (increased by ability str, 95% cap) in darker rooms.
Nice bonus, sadly is not super reliable.

Prism (4) fires a prism that shoots lasers in all direction, dealing Radiation damage. Blinds enemies on detonation.
Prism's damage increases when bathed in light, but is capped.

Build
Aura is up to personal preference, [Brief Respite] helps with survivability, granting back some shield for that sweet 0.3s invulnerability (up to a second if the shield replenishes entirely).
[Preparation] is a nice QoL. [Primed Sure Footed] is obviously a nice choice, especially if you combine this build with weapons that have radial effects. You will probably need to switch [Blind Rage] for [Transient Fortitude] so energy is less of a problem.
Speaking of which, [Blind Rage] grants a massive ability strength boost, making it up for [Overextended]'s malus, as well as providing high energy costs, further helping shield gating thanks to Brief Respite.
Rolling Guard further increases survivability, by granting short windows of invulnerability - it also cleanses any debuff.
[Primed Flow] so we can use more than 2 skills every minute.
[Natural Talent] is a must in such build, since Prism's animation takes forever.
[Prism Guard] makes it so we are the prism, pretty much killing anything that we encounter. Its tiny base duration (4s) forces us to build for high duration, hence our last two slots are for [Primed Continuity] and [Narrow Minded].

Helminth
Sleight of Hand (2) has pretty much no use in such setup, so slot 2 can be replaced.
I personally went for more mobility (Infested Mobility), mostly because I use it in scenarios where the prism pretty much kills anything on sight. Similar options : [Firewalker] ([Nezha]), which grants status immunity aswell, but a relatively low movement speed bonus ; Reave (Revenant), is not super practical in tight/vertical tilesets, but great choice aswell.
While I did not try, Nourish could easily be an option, adding more damage and energy sustain to the build.

Arcanes
Energize simply generates a lot of energy in case the mission lasts longer/requires more casts to kill enemies.
Molt Efficiency grants more duration, which makes it so we don't have to use our skill as much - less energy hungry yey.
Molt Augmented is also to be considered if you switch some mods up, Blind Rage. Having over 100% ability strength is highly recommended - if you start the mission with say 80%, this will rapidly compensate for the negative str.

Archon Shards
This build is playable with no Archon Shards. Spending some to further reduce casting time, or to increase ability duration/energy orb efficiency are some viable options.

Gameplay
Press 3/1, run.
Bullet Jump-Cast 4 and refresh when necessary (it kills the bad guys!)
2 when you want/need to catch up/gotta go fast.
