We got computers (pet yard), genetic modification (nest, mad lab) so I’d say pretty modern.
Few use gunpowder probably because of how powerful and accessible the magic in the realm is. Bilgewater’s cannons blasts do similar damage to titaniums, but probably are harder to come by since I’d assume natural magic replenishes over time, while gunpowder must be made and cannonballs cast.
Standard automatic firearms probably wouldn’t do much against more powerful enemies, and each individual bullet would be rather cumbersome to seriously enhance with magic, hence why items like the thousand shot or covert, while fast to fire (and probably magic enhanced, to an extent at least), are less effective against enemies with higher defensive capabilities.
