1. no 2. one with crush for waterfiends, i use chaotic maul, another option is zammy spear, (i dont like gs's) 3.you wont need many, i cant remmeber exactly how many i used when i did it, but its not many at all per task, each task varies anyways 4. cannon is worth it 100% on every task possable, (if you can use it ofc) it speeds up kills by a fair amount (make sure you place it by spawn spots) bring around 3k c balls just to be sure, i never used more than that. its usualy 8 c balls per kill i think thats what i averaged at. 5.i got 99 slayer before infernal ashes ¬_¬, but imo i would use urns the banking etc, would make it highly annoying, (unless you have yak then just use yak to deposit 150 per hour) otherwise i would use urns, 6. black demons are my favourite task!!! kill them at taverly dungeon, with cannon and piety / turm and melee you can either prayer melee to be on safe side but all i ever did was high def armour and uni/buny that was enough, i think i killed 200+ easily in less than a hour = good xp, and there 3rd best charm dropper rate 7.bunyip for most tasks, and bob for some tasks when needed, only use unicorn on tasks where you get hit loads, so no need for like abby demons (like i always see people do it annoys me) 8. doesnt matter even if prayer potions rise again to liek 7k ea its still worth slaying with piety
