Charge Blast Boost
Charge Blast Boost increases blast radius and is marked compatible with Charge and Surge in the supplied mod table.
How it works
The Mods page lists Charge Blast Boost with a maximum bonus of +125%. Its compatibility marks appear under Charge and Surge. The page also states that weapon mods can be attached to the Service Weapon and mainly concern damage or ammunition; the stated effect here is specifically blast radius. The source does not describe a different effect for either compatible form.
