But the -1 is always there one time I was using a 2, -1 bow and my character was injuried with only about 25% health when we went to a cinematic in a mission one person didn't skip and I was dead when the cinematic was over. If you want to use this type weapon in battle I suggest keeping another weapon equipted to run around with. Haven't used a vamperic weapon since that eposide.
i never really liked casting mending on myself... rangers need all the energy they can get so having +3 energy regen is a must IMO
i use a 5:1 vamp myself... i like to keep out my long or storm bow until the enemy gets too close at which point i switch to my short bow that has the vamp... this way i don't lose like half my HP b4 the battle even starts
