agree... the fishing mechanic needs a bit of work imho..
1: having a Harpoon that cant catch fish :-(
2: trying to build waterline fish traps with earth or wood so fish get trapped in storms :-(
3: no burley or fish attractant
4: Harpooning a leviathan should give us a free underwater journey (to somewhere??) secret destination? or run us out of air if low swimming stamina...
5: if underwater,releasing catch from harpoon should surface us relatively quickly.. and with good swim skill experience.. we should be able to have stamina left for a short ish swim ...or improve stamina in water whilst near a boat ??
