Mid level templar can be both extremely versatile as well as bait for wasting enemy actions with parry.
As with every other class in the game, Reapers have access to unique skills and pieces of equipment - they use a special, Reaper-only sniper rifle and Claymore explosives. The Reaper is the first new class of the three (the other being Skirmisher and Templar) introduced in the War of the Chosen add-on.
