Diablo 1 HD Hellfire Mod | Awake

So i have 25 level Rogue and my items are pretty bad. I can't progress because mobs in Izual location are my nemesis at this moment(guys with charge).

What am i doing wrong? I have only full arctic set(probably bad luck, other bows didn't have very fast attack speed). In Diablo 1 there are no mercs so how do you progress with Rogue? Golem is very squishy at 2 level so it is pointless to summon him.

I read that i must put every single point into dexterity so i added every single point to this stat.

Probably i should grind in Hell 14-15 so... Which one stats should i look for? Except resists ofcourse.

Here is a guide for classic diablo rogue. Probably wont differ too much.
U need +life items, high dmg to stun enemies,...+ mana and life leech
All to dex is possible, cause 1 to vita=1life - not worth spending. edit: I did Izual just now with rogue, 25lvl, in Arctic set, amul- maiden broach, rings - +2atrib, +10atrib some res and life. Just move slow and take them one by one. Izual - teleport and guided arrow.
