Check out the Psalm code 'Hermeticon Psalm + Galvanic Psalm + Iron Psalm' as it applies the effect 'All Physical Damage is converted to Warp Damage & Gain +20% Warp Damage'. If your weapon at least does physical damage then you could convert it to warp damage and benefit this way. You can easily fit this 3 psalm code into an Innoculator and/or Main Implant then also include a 'Uncreator Psalm + Binharic Psalm + Static-burst Psalm' for +50% Warp damage into the other.

Lastly, add a 'Neuralis Psalm + Transonic Psalm + Hypergheist Psalm + Phosphoenic Psalm' into a 4 socket weapon for +100% warp damage or a 'Animus Psalm + Electro-haze Psalm + Voltagheist Psalm + Nova Psalm + Shroud Psalm' into a 5 socket weapon for +50% Warp Damage and Warp Resistance of enemies is halved.
