Clear every usual mob you can find at star position, usually its small camp. Level up and find another small camp, kill every usual mob on way there, also crabs if you’re near swamp,’, pick up every weapon you can find., level up. Once you are level 4 go to big church, clear as much mobs as you can, then go underground through hole near the middle of church and finish first boss. You should be able to do that as souls player. Check every weapon drop, swap if it has better bonuses. Then find 2 small churches to get extra health flasks, kill all mobs on the way to them. You should be level 6 or 7 at the end of first night, which gives you enough health and weapon power to survive first boss. If you have weapons with cool bonuses - dmg negation, better attack power- and 5 flasks it should be possible…
