braziers last a good while and coal is pretty easy to come by... theres also the flame sword in addition to Mythicbuilds list but they have to be spawned in
I would love to have a play session with you at some point in the future. that being said I would love to hear of more build contests myself and also recommend (if it dosent already exist) steam group(s) much like the space engineers [UESC] clan that used to organize monthly contests much like here focused around building and scored much similarly to valheimians contests steamcommunity.com/id/berubea0815
