A routine slayer helm is Face Mask

A routine slayer helm is Face Mask, Nose Peg, Spiny Helm, and Black Mask like arham said. To make it a full slayer helm you will have to OSRS gold add a Focus Sight along with a Hexcrest for your slayer helm. For the master, a general rule for Slayer is to just use your very best master, however if you'd like the fastest points you can do 9 jobs with Mazchena (sp?) , the demon man in Canifis, then do your 10th tasks together with your highest available master (Sumona+).

I'll purchase the berserker ring then, and prayer fostering armor. I am only able to use the 15% assault and strength bonus prayer though, not yet chivalry or piety. Super potions are the reccomended thing then, right? I would like to train strength, which means you've been stating d scim, SS, or korassi's (that I don't currently have). I have obtained the RFD gloves, but maybe not yet nez. Is black mask ok until complete slayer helm? I'll use earmuffs and other head things rather until then also. Is your prossy hauberk better than fighter torso?

Can it be ok if I don't use pots or beg on non levelled stuff? A friend of mine said that I wanted 55 crafting to make the slayer helm, even if I use points to learn how to make it. Is that true? Can Verac's armor be really good? It's high defence stats, and also a good prayer bonus. Can I substitute one for my own skillcape?

It's ok to jump out on the prayer but it will not be as fast. Everyone's giving you advice for the fastest, most effective slaying... cutting corners will all result in it being even on buy RS gold lower leveled stuff.
