Your projector canisters reduce partial cover by one step (from three-quarters to half or half to one-quarter). If a creature has one-quarter cover, you ignore it entirely.
When using a projector canister that requires a saving throw and deals damage, you can take a penalty to the save DC equal to your proficiency bonus. If you do so, the item's damage increases by an amount equal to your proficiency bonus.
