A low-level standard to the Faithful Spearman I posted earlier.
I use this to Coop with people with occasional invasions in the Depths or Blighttown.
Obviously less endurance will mean less versatility to work with on this, as it was specifically geared to work with the winged spear. A few options like the Falchion or Scimatar are available, but that just makes things TOO easy.
