With your current stats, I'd cancel the task since it'd take a real long time. But if you want to, just wear prost top/bottom, slayer helm/black mask, fury, whip, anti shield, d boots, and barrow gloves/highest rfd gloves. Inventory should be like 8 ppots, 4 antifire pots, 2 super sets, bronze axe, 875 gold. For blocking, summona gives different tasks than duradel so it'll be a waste of points if you block now. Generally, people block irons, steels, warped terrorbirds, greater demons, scarabs.
