Cheers lads!

I had what felt like a slo-mo version of that! My last trophy wthat i needed was the one for
the best weapon through magic reinforcement. 'Grand' says i, there's a
+9 Magic Falchion sitting in my inventory, so all i had to do was claim the blue titanite slab in the crystal caves, and the large magic ember in the archives. So i fought my way through the archives, and despite having 40 health (and still wearing the
ring of favour and protection, i still got one shotted by the channelers a few times. But i persevered, got to the cave, used all but 1 of my 99 prism stones to
find the path to the slab, grab it, warp out, and head off to ythe guy in NL Ruins to upgrade that falchion! But my enthusiasm for grabbing the slab made me forget about the ember... so back i go, died 3 times getting back to
Seath's lair impatience more than anything, got there and forgot that
i had yet to kill Seath at the end of the cave so he wouldn't appear here, arrrggghhhh! 
. So all in all, i got the trophy about an hour after i said 'yes, have it now!'. And then there was that slo mo that you mentioned after the trophy needed for the PLatinum... ... ... oh, there it goes!
I'm just glad i've finally rinsed this game (i really couldn't put it down) as i've vastly reduced gaming time because of Uni commitments and i've a fair few neglected titles on my shelf to boot. So i'm probably gonna start into that mostly unplayed copy of Demon's Souls i have, haha!
