Just stats I just started Ls and have no clue lol what should i be doing for the stats?

With a fighter you'll want to probably use all strength and dexterity, or possibly put the first 10 into vitality and then all str/dex.
Dexterity can vary depending what weapon type you use, but 100-130 is a safe range generally with your MQ gear on.

i go into the catacombs and get killed instantly lol.

i suggest you to put 130 in dexterity and the est in strg

120 dex(swords/clubs)
90dex(other weapons)

rest str


high ee weapons (LS/DEX/STR is usefull)
dex/str Armor/Charm (LS / EE(ARMORS) is usefull)
