Blast Psion is one of the Vek from Into The Breach.
Description[ | ]
The jellyfish-like Psions act as support units, providing passive bonuses to the Vek. The Blast Psion is distinguished by its light grey coloration and bright orange cranial nodes. This Psion's presence causes other Vek to explode upon death, damaging adjacent tiles. The ability granted to the other Vek is called 
Explosive Decay.
The Blast Psion can never spawn on missions with explosive mines, even if they are the Psion for the Archive, Inc. island.
Strategy[ | ]
The Blast Psion can complicate the resolution of any enemy on the map, as any enemy that dies will explode and deal collateral damage. If the Blast Psion can't be immediately taken out, look for weapons that can nullify other targets by either cancelling their attacks or pushing them away from buildings. It is possible to use the explosive decay effect to the players advantage to damage other Vek, provided caution is exercised in preventing collateral damage to the grid.
- Vek will not explode if Blast Psion also dies as part of the same attack resolution. E.g. if you push a regular Leaper into a 1HP Blast Psion, the attack will kill them both and the Leaper won't explode. However, in sequenced deaths where Blast Psion dies as part of series of other deaths, explosions will continue to happen until Blast Psion dies as part of a separate attack resolution.[1]
- Vek explosions triggered by emerging Vek are processed after all Vek have finished emerging from underground. This may lead to unplanned outcomes when an explosive Vek dies due to blocking a spawn point located adjacent to another spawn point. In this case, the Vek who emerges from the adjacent spawn point will be damaged by the explosion.[2]
- If you kill a Vek with Explosive Decay by pushing it into a pit, the explosion will still damage adjacent tiles.
