Does anyone know where to buy a staff with DS focus on it? I heard there was a named mob in Sals that drops one? can anyone confirm? Thanks!!!

you can buy staves with all focus (incl. deathsight) from staff merchants all around Albion.
in Camelot the merchant is named Floree.

the staves are pretty expensive, but you get half the money back when you sell them back.

i would like to know about any drops too. i don't know if there's is any outside SI.
and for a necro the epic gives good staves at lvl20 and lvl30. so do this as soon as possible.

Shimmering Staff of Enhanced Necrology has 50 DeathSight Focus on it! if you buy it for over 150g, you paid too much!
