I am just Strength/stamina atm. I started with a high dex, and occasionally put the odd point in that as well. Not totally sure what adaptability is, but it seems to affect poise, which you can never have enough of so I have started putting a few in that as well. I am using the ******* Sword+5, with the Drangleic chest armour, wanderer everything else.
Made a lot of progress last night. Some of it very satisfying, some of it incredibly frustrating!...I went through the Cathedral of the Blue and killed both bosses quite easily, same with No Man's Wharf, two good areas! Then I went back to Lost Bastille and took out the Ruin Sentinels and Gargoyles. I then messed about a bit with summoning/invasions for a while(beat the Gargoyles about 4-5 times with different people.
Then comes the most frustrating boss so far for me by a mile...Lost Sinner. First time, I very nearly did it solo, got it down to about 2 hits, but then was killed. The subsequent time I tried it, with an NPC summon, I was killed very easily. Must have tried it about 6-7 times!...in the end at about 3am, I gave it one last go and managed to do it. The NPC summon for that fight is worse than useless! most times she barely made it to the fog door.
