Mortis Thorn

Mortis Thorn can be obtained by trading in 75 Patient Cards. These in turn can be obtained by trading in Arachnophobia (Black Widow mech. brigade) or Spider Exterminator (Spider mech. brigade) convoy marks at the quartermaster, at the rate of 3 marks for 1 card, or at the Catacombs shop at the price of 42 diary pages for 5 cards.

In battle, Mortis uses a pistol with decent range and fire rate, but low overall damage, so he is generally more effective as a support unit.
