50-100 euro can get u a +7 Elmore cloak on event right now.
A +8 light set would be one of my first suggestions to get 10% reuse.
After that, focus on all crit dmg, then skill power. Top augment stones are cheap at the moment to get 20% crit dmg on the Daggers. Invest in 2x kain 5-8s for death fire. Use temp jewels from store.
After that, get lvl 3 artifact book and lvl 1 agathions bracelet. Focus on +4 balance artifacts 1st and +4/5 aries and scorpio.
Always fo us on crit dmg. Skill crit dmg, patk crit dmg, doesn't matter, always crit dmg. If you have a choice between Def and crit dmg, crit dmg is always the answer. Skill power after that. The +8 light set is a must tho.
Are u using prestige?
Edit: also, 450 those Daggers if they aren't already.
