hehe
yea heres what you need
looking at your inventory, you need to not be afraid to shrine things, if you don't know how to shrine, you just take a crap item and give it to mu'rakar, and he gives your life and mana back instantly.
and every item in your inventory would go great to him. makes things a lot faster instead of regening.
also the items y ou have on are good, but you are 15 now, so you need a 15 wpn to with some ee to make it easier, but the one your using now will work, the armor needs changed to some 15+str armor and the same for the charm.
defense in softcore is not needed barely at all. and early on in your build dex really isn't worth it, since your doing pure str i see stick with that till later levels where you can buy a 20+ str dex armor or charm for cheap.
Other than that try to get into a catacomb group and get some easier lvls taht way makes things a little better i would say

as always you can pm me if you want more help ofc
