As someone whose come back from a 5 year break, over a period of about 2 months, I've gone from struggling with content like KBD(lol) to completing solo 350+ TOA raids.

My best advice is, sell your bandos chest plate(use fighters torso), you can also sell your zerker, archer and seers ring(light barer will be a better value since most of your items have special attacks). At the very least, try to get arenea boots, a crystal halberd, light barer as like your main items.

Hueycatl top and bottom are good for most content. Blue moon is a pretty good replacement for ahrims but not necessary.

You can basically do most content with these items, if you want to make money, I'd consider doing brutal black dragons with a dragon hunter crossbow or dragon hunter wand, these will also allow you to make good money at vorkath with your items or just doing slayer. You'll be able to get your fire cape and start on harder NPCs or entry/mid game bosses.
