Changed out [Growing Power] with [Brief Respite] since the benefits were marginal if your attention was split.

Inspired by the many similar builds out there. Stationary [Protea] for teams playing defense or similar missions. Preferably played with a [Wisp] for survivability due to the lack of [Vitality], [Redirection], or [Adaptation]. Arcane Eruption could be replaced with Arcane Aegis, [Guardian], Pulse, Barrier, Grace, Tickery, etc.

If you're having problems staying alive, switch [Power Drift] with [Preparation], and Arcane Eruption with Arcane Aegis or [Guardian] (preferably Aegis).
If you are paying more attention and could use the extra strength, switch out Brief Respite with Growing Power.

You could probably play with minimal attention when paired with:

• 2 Wisp Specters
• 1 Octavia Specter for extra energy, mallet, resonator, and metronome if you can get used to the default song.
• 1 Nidus Specter for 28% ability strength from Parasitic Link.
• Max Minions Summons from every player.
• 1 Nezah with Safeguard to keep all the Specters alive.
• Last 2 slots can be filled in depending on the level of interaction people can provide or map:
  - 2 Wukongs with Celestial Stomp and either Kuva Bramma or Acceltra
  - A combination of Khora, Strength/Reach Octavia, or Wukong.
  - A combination of Khora, Saryn (if you can target), or Wukong.
  - A combination of Khora, Nova (speedva if survability isn't a problem or slowva if the map is really small), or Wukong.
  - 2 Equinoxes cascading their [Maim] nukes (depending on map size or if you can time it consistently).
