It's ok to skip out on your prayer, but it's probably not as RuneScape gold speedy. Everyone's offering you advice for the fastestand most efficient beating... Cutting corners will all result in slowing down, even in lower levels of stuff. But , you can do what suits you. If you're like desert lizards or something similar to Turael, then yeah you should be good. But you're probably not going to the same as him.
If you use full verac, it's going to be more in repair costs. Not really worth it, and less prayer, compared to using proselyte on a platebody. Yes, black mask is okay. In fact, you ought to be wearing it unless and until you have an undead task, then you can use the salve amulet and whatever type of helmet you'd like.
A final point is that you should have a cannon at all times you are able to. Even in single combat areas, it's possible to cover up areas that the cannon will be able to strike everything in the room regardless. Additionally, I'm going to suggest an alternative to the Brackish Blade, unless the 500k for it is too high after all other things.
A lot of monsters you encounter while slaying are weak to stab. Brackish Blade is equal to the Dragon Scimitar except in stab instead of slash. It has a strong stab also, so you are able to build strength. Do not hesitate to suggest Piety. It's amazing. Get 70 prayer as soon as you have the money to do so. Super sets are also good.
Why did you tell us all your stats? Anyway, full rune, the neitz, the Dragon scimi/long, if your lazy, regen brace, or if you think you'll die wearing barrows gloves(Obtaining the items back from runescape gold 2007 culiamancers will be easy) and you are a big fan of questing (In this case , just use Scimi) you can earn dragon boots, barrows gloves seeing your only one level fame, Obby Cape, Dragon Def, RoW/Zerker if truly want it.
