|“||Confers additional damage based on weapon tech level to Suppression and all area-effect abilities.||”|
– In-Game Description, XCOM: Enemy Unknown
The additional damage is one point per weapon tech level, and can go from one with the LMG to the maximum of three when equipped with the Heavy Plasma. The damage is unavoidable. If the soldier also has Danger Zone, this essentially turns the Suppression ability into something like a weaker but spammable grenade. It also increases the damage output of the Rocket Launcher and the Blaster Launcher by +2 and +3 respectively. It does not increase the damage output of grenades.
