Answered Slayer setup help

Dont range unless you want range xp. Its too slow. If you do range, stick with slayer helm. 15% is better than 10% given by void.
Only mage Ice strykes and ganos.
If you already have ahrims, id use that instead of gano. Cheaper to repair, and only 1 less mage attack.
Melee everything else. If youre rich, full bandos, and turm everything. If you're a bit short on cash, Bandos tassets, and prosylete Top.
For tasks where the cannon does most of the damage, like Black demons, dark beasts, and aberrant spectres, i use full prossy.

Im sure by know, you know what can help you go faster and what wont. Just mess around with different set-ups for different tasks, till you find what you like.

Obviously skip slow tasks.
