23.

can i compete with this gear?

snipers helm
pink candle
arties
snipe wing

or should i use alch for regen?

Use lvl 23 sandstonecave wings, they give 2 more armor, i believe but one less hit. You can always use 22 int for alch and play using artisan... :/ and i hope the snipers helm u are talking about is also a lvl 23 helm xD
