So far, it's working very good and I only have to OSRS gold bank when I can't hold any further drops. You're seriously better off using a whip rather than Guthan's warfare asses. The damage per minute of the spear is awful, so just re-banking once you need to is faster. Switch to a whip if you don't have to cure then. Simple to solve.
Helm: Total Slayer Helmet - While I am not killing them to get a slayer job, the Total Slayer Helm supplies excellent defence to get a ranged helm, as well as gives a bonus to ranged attack, even when I don't receive the 15% incentive because it isn't a slayer job. Amulet: Armadyl Pendant - Cheap Armadyl item. I currently have an offer in to get an Armadyl Stole to substitute it, but it likely won't buy for a little bit.
Body: Saradomin Body - aids get to Armadyl's Eyrie, and allows me to kill Aviansies at the center field of this God Wars Dungeon in case the eyrie gets too crowded (but it usually doesn't). Legs: Dragon Plateskirt - While approving a ranged attack penalty, the excellent triumphed defence counteracts that. 1 day I may replace with Dragon Platelegs to seem somewhat better, but it just isn't cheap for me.
Cape: Ava Accumulator - Who wouldn't utilize this while that range? Weapon: Rune Crossbow - Great one-handed ranged weapon. Can't wait till dragon comes out! Hands: Zamorak Vambraces - Zamorak thing with nice scope bonus to help offset the penalties of cheap RS gold other equipment. Ammo: Broad-Tipped Bolts - Affordable and great ranged strength bonus! Not a bad trade-off.
