Hi, ive played LS a little.. ive got a 27 fighter here he is

Strenght 97
Dexterity 52
Intelligence 10
Vitality 55

Weapon: Magical fine alloy sword, 18-188 dmg 40%ee
Armor: Magical bronze plate mail, 14 str
Charm: Mystical lightning III 14 str

and i can barely kill 1 monster in the arena.. i hit like 5,60,5,250,5,5,5,5,5,5,,5,5,5,5,5,5,5,
what am i doing wrong? i just want to do a climb.. find some nice items.. any other char better for this? and im not gonna spend all my fg either for a good char...

With your sword, your going to hit very high and very low.
If you want more consistent damage, I'd recommend going with an axe or club.

Try to get more EE and more stats on your items, but if you're too poor, try catacombing.

I decided to go a Wellermage whatever that is since they get alot of nice items ive heard, but its still really hard to level since i cant afford the 1 million ee gear

LOL
You don't really need 1 million ee gear, though it'd be really helpfull if you did

A "wellermage" is just a mage that wells white items.

Arent they good then? besides.. i have 0% idea what to pick up in catacombs.. so many items, so many players.. xD

Yes, they're very useful characters to have.
