whats the best money making slayer master?

and also what would be the best slayer master for me?

i have 66slayer, slayer helm, 99atk, 99str, 90def, 99hp, cb level 125, only plan on using melee, bandos gear, bgs, dfs, whip, and i might get chaotic rapier.

im currently using sumona, the pollnivneach slayer master

Get rapier. No idea why you would want a bgs for slayer. DFS is only good for skeletal wyvern tasks, which require 72 slayer. Use a dragon defender. Use duradel in shilo village, and kuradel once you get 75 slayer.

Mister moocky covered it pretty well. You should always be doing the best slayer master you can do. This will both maximize exp and profit from slaying.

The base slayer gear is as follows (alternatives in brackets):

• [For all slayer monsters except those mentioned under other weapons] Chaotic rapier (whip)
  
• Bandos body + legs (Verac's skirt with either fighter torso or proselyte top)
  
• [Depending on prayer/accuracy needs] Fire cape/Soul Wars cape/Ardougne cloak 3
  
• Barrows gloves (your best rfd gloves, at least rune)
  
• Dragon boots (rune boots)
  
• Amulet of fury (glory)
  
• Dragon defender (rune defender)
  
• Berserker ring (i)/ferocious ring if slaying in Kuradal's Dungeon (berserker ring, warrior ring)
  
• [Most important] Full slayer helmet.
  
• [For magic defence on waterfiends/aquanites] Karil's top and elite void skirt (black dragonhide body and chaps)
  
• [Crush attacks to use on waterfiends] Chaotic maul (Saradomin sword, Zamorakian spear)
  
• [stab attacks for higher-levelled dragons, when not using rapier] Korasi's sword (Zamorakian spear, leaf-bladed sword)
  
• Task-specific items such as mirror shields, antifire shields/potions, elemental shields, rock hammers, crystal chimes
  
• Cannon (optional, up to personal preference)
  

Slayer setups generally emphasise strength bonus, which increases the average damage of each succesful hit (slayer monsters usually having rather low defence, hitting is not a problem). Secondly, prayer bonus is important to keep the cost of prayer potions down (as you slay with piety on, to increase the speed of your kills. This is cost-effective and highly recommended). As a rule of thumb, +15 prayer bonus or above is good, but don't overdo it (anything above +25 is a waste). Defence and accuracy bonus are usually not fretted over (any defence bonus over 200 will do; if you get hit too often you should be using a protection prayer). Dagganoth, black demon, lesser demon, hellhound, bloodveld and spectre tasks should be cannoned, as it dramatically increases xp rates (although it costs a bit).

 

Some notes on gear: You'll want a fury and a berserker ring before you get bandos plate, and get that before tassets. You'll want accuracy bonus on higher-levelled dragons; if using stab attacks (which you should) you can use the Ardougne cloak 3 which provides you with +6 stab and +6 prayer bonus. Torso + sw cape and fire cape + proselyte are common cheap top/cape combinations; the former is better.

 

Some levels to get for slayer (in approximate order but I'm not sure on the summoning):

• 68 summoning - bunyip
  
• 81 dungeoneering (you need 2 million xp, which takes you to level 80, but allowing some tokens for the scroll of life) - rapier
  
• 89 herblore (85 with a +4 stew boost) - extreme potions, superantifires
  
• 95 prayer - turmoil and soul split
  
• 88 summoning - unicorn
  
• 96 herblore (91 with a +5 stew boost) - overload
  
• 99 summoning - steel titan
  

I'm sure I missed something but this is most of it.

 

For you personally, GET 70 PRAYER. Get that rapier, sell bgs and dfs and dump the money on prayer. At this point I'm 125 combat as well and probably slaying twice as fast as you are due to the handy skills mentioned above.
