Whats the best way to kill entities without anything from War of light?

Hammer, no seriously the Phoenix Buster Ironman might be worth looking into.

Yeah he seems to be my obvious thing to look in to. But he is verry difficult to protect being a double base big fig.

Why? Just curious as to what your reasoning is behind that.

Capture/Elaborate Deathtrap, Incapacitate, Pulse Wave or Penetrating Poison.

Phoenix buster seems right, but begs a question, can a possessed figure use the Entity's giant size? If that's what activates the PBIMan then the possessed could use it?

Entities are tricky too, since a PBIMan can be possessed and makes an even 200 points, thus getting the ability to also kill giant size PBIMAN that you use.

With a seemingly innocent entity like Proselyte the possessed can use barrier to set up his shot.

The entities do not grant combat abilities such as Giant Size to the figure they are possessing. They grant the possessed trait and the entity's keywords.

They gain the cosmic Keyword. Which is good for PBIM.
