Yesterday I was checking Soul frags quest and I discovered that there is only one in floor 1 (chaos floor) that gives you 25 frags and one in floor 2 (death floor) that gives you 50 frags. But there is no quest for soul frags on 3f floor (yahee floor) where monsters are harder.
On the other side, in Varlok temple we have a blood frags quest for every room (water, fire, earth, wind).
So my suggestion:
Could be possible to add a soul frag quest on Shadow temple 3f?
Following the quest 102 and 112 Soul Drag... I mean Frag and Soul Drag 2!
Something like:
Soul Drag 3!
Guardsman of yahee (fallen Demon) x 25
Guardsman of yahee (cavalry) x 25
Guardsman of yahee (fallen succ.) x 25
Reward fragment of soul stone x 75
Notes: monsters in 3f spawn less than in 2f and you can't random tele, since they are harder to kill, then I choosed the 3 more difficult monsters to kill, so the quest is hard to get and harder to complete, that's the reason for me to suggest like this.
