When I first started, I used
Disguise armor (causes silence when being attacked)
Mistress Angel wing ears
2x Sting Gloves
Eddga Shoes
Deviling Muffler
Khalitzburg Guard
Quad drops rod
Kaho
Disguise card should be fairly cheap because it is very common
Mistress midgear would be 25-30m
Sting gloves are I think...7-8m
Eddga shoes...I am unsure but I think they are around 15m.
Deviling cards used to be 20+m but can be found for less than 10m now due to the halloween event. If you can't afford a deviling, settle for a raydric muffer. It's cheaper.
Quad Drops will give more dex and costs about a 1m (same with a Survivors Dex Rod)
Kaho will be the most expensive thing. It will cost about 90m
For guards, you can use khalitzburg, tirfing, or teddy bear. Tirfing is probably best though.
