Robo doesnt give lvl 30 weapon, he gives out lvl 40 weapon from the gift box... u could also possibly get a lvl 28 pants from robo.. but by the time u join it, u'll probably already hv those pants already... but if u're that broke, i guess u've got some hope there.. (but the chances are low, so u gotta go into A LOT of KQs)

Level 30 Armour, Lvl 34 boots, and Level 36 helmet you get from quest.

I guess you can try Zombie King in Graveyard and he drops lvl 30 weapons, but you hv to go in a good party that u can trust (its pretty dangerous there, its like the Marlone in Hideout)... and hopefully they'll drop u a mace or hammer... and ur party will let u keep it

but u cant get into Graveyard until lvl 30 (the map is level restricted for 30-39)

And even if they drop u a weapon that's not of your class, u can always vend it (most ZK weapons are worth 60-80s), it will definitely give enough silvers to buy a lvl 30 weapon from NPC.
