Some advice going for 120 slayer:
Dark Magic: Best aura you can get, use it on the highest xp tasks like Airuts of difficult ones like Rune Dragons where that 15% dps will make the difference between life and death.
Mahjarrat: Would be worse than Dark Magic but better than berserk auras due to longer duration/less damage taken I think. However, I don’t have VIP so not sure.
Berserker auras (10% dps, ruins your defence): These are a great dps boost (especially the first 6 minutes where it will stack with ovl if ovl aready on when you use aura, raising stats to 127) but you can also get destroyed so I tend to avoid them on anything which hits hard (airuts/edimmus/rune dragons/shapeshifters etc). On weak monsters, especially the fast tasks, these are fantastic:
Celestials (doesnt last full task)
Dark Beasts etc
Accuracy Auras: WHile in pvm these are the best dps if you don’t have 100% accuracy, they’re not great for slayer as long as you have t90. If you have t80 use them at Airuts/Kal’gerions and other high defence stuff.
Penance/Vamp: Not particularly useful but might as well use them if dps auras are on cooldown as it makes a task cheaper. Penance is great for aviansies tasks.
Scythe > Lance > Drygores = Attuned Crystal Hally.
Drygores can be good for automatons for safety. Danklight/OH Drygore for Ripper Demons.
Nox Bow > Ascensions as Dazing Shot > Needle Strike, plus greater max range.
Supreme Overloads (1% accuracy/2% dmg over normal Overloads) plus they’re cheaper per dose. Use them everywhere, the more dps you do = faster kills = pays for higher cost/h
Adrenaline Potions (1-3 per task). Most useful as melee but pretty good on all styles.
Ring of Vigor to save 10 adrenaline after ultimate. Can squeeze in 2 wild magics during sunshine with it + adren pot.
Elite Enhanced Excalibur. 40% of lp every 5 minutes, doesn’t waste adrenaline like butterflies/rejuv etc.
Boots/Gloves = Barrows Gloves + Silverhawk boots are the best cheap power armour you’ll find, plus hybrid so can use all tasks.
Bandos/Arma/Subj boots+gloves if you have a bit more gp, still no repair cost but more dmg than the hybrid ones. T80/t90 is a waste of money for 2*0.087% dps, both upkeep and higher cost at death. Likewise, deathtouched brace isnt worth the cost.
Blood necklaces (Brawler/Farsigh/Arcane Stream) have the second best dmg in the game on non reflect-immune monsters, above Ammy of Souls. Use them all the time (Dragon Rider is better than non-blood arcane stream though) unless you actually need the tank benefits of Souls.
In no way is the Demon Horn necklace worth it. Prayer potions with t95 prayer + soulsplit = 40-50k/h cost, and much greater dmg boost. Stock up on tons of prayer potions.Just as a disclaimer, if you don’t care that’s fine. Hava asked me for some advice as he’s going for 120 slayer but as he had to go before I could tell everyone I thought it’d be easier to write everything down here.
Gem Bag + toolbelted Herbicide/Charming Imp/Bonecrusher (I crush everything except Rune/Addy Dragon bones)/[Seedicide(all but yew+/papaya+)
Spring Cleaner’s great, no looting + it profits. Alch Runes for the rest. Notepaper is for Muspahs as can’t alch, and the odd valuable drops which you don’t want to alch and have more than one of/rune drag bones etc.
Dom Tower gloves have uses, but aren’t essential. I use them at K’ril, Kree, Kal’gerions and Rune Dragons.
Steel Titan everywhere, with Steel of Legends Scrolls.
Exceptions are Ice Nihil (smoke is cheaper, slightly worse version) for maging Kal’gerions.
This is what I’ve found works best. I generally come out even/small point profit with the 10/50/100 bonus points increasing my total, which I use to buy additional reapers. I went down the list of tasks assigned by Morvran from highest to lowest threshold and blocked all of the ones I skip every time. There’s other tasks I skip also, but the blocked tasks are the most common ones.
All of my preferred tasks are at least 250k/h Slayer experience, and are ones I enjoy too. There’s a handful of tasks that could be preferred which are better but I don’t like killing them.
Automatons – Scythe > Range for xp/h. Dw drygores is almost as fast but 99x safer.
Kal’gerions – I like magic best, but can melee em too. Nihil + t90 is 100% accuracy. Demon Slayer gloves/boots (can be dropped by them) gives a xp/dmg boost.
Abyssal Demons – Magic > Scythe (demon slayer gloves/boosts again)
Aviansies – Magic > Range for Kree, but difference is marginal (Dom Tower Gloves/Nips/Glacor Cave boost etc make a diff), Penance for 0 sups
Crystal Shapeshifters – Melee > Magic. Barge + Surge between enemies. Attuned Crystal gloves + boots (750 crystals each) on shapeshifters adds 10% dmg, sending them to 290k/h xp plus 680k combat xp.
These are the other tasks I do:
Elves – incredible xp/h, but the task only lasts 10 minutes with Scythe
Dark Beasts – I hate these so cancel them 90% of the time, but they’re technically a great task.
Edimmu – boring, but ~200k/h and very profitable. Melee > Magic, magic is far far safer
Shadow Creatures – Scythe > Magic
Muspah – Ancients
Ripper Demons – DW melee is best here, and they average 4-600k/h slayer exp, but they’re dangerous as hell so I don’t bother.
Camel Warriors/Acheron Mammoth – Again, I don’t kill them but mean to start as they’re amazing xp if you don’t suck.
Chaos Giants – Scythe
1 = Dw, 4 = 2H, 2 = Range (Needle Strike/Dazing Shot can switch), 5 = Magic (if dual-wield Conc. Blast replaces Sonic Wave).
Tuska’s wraths hould replace Sacrifice/Smash for 2h, but I don’t have it.
Dw setup is slightly wrong, should be same as the 2h ones except for thresholds/ability 1.
For melee, Fury and for dw magic, Concentrated Blast have to be clipped or they’re useless and should be removed. After you hit once with them you use the next ability instead of letting them compete cast.
Snipe should either queue an ability so it activates instantly (cancelling cast time, doesn’t always work if you lag) or by using a new ability before cast finishes (will still hit). Again, if you’re lazy and just revoing everything get rid of snipe.
Weapons: Precise 5 (5x Armadyl – if dual-wield put it on off-hand) + Aftershock 3 (5x Illujankan – from Zaros stuff)
Armour: Genocidal+Crackling2 (2 undead/3 explosive, like 20% chance).
Biting2 (5x Subtle)
For my remaining two perk slots I use pvm ones as I prefer to just use my t80 nex gear everywhere.
Absorbative2/Venomblood (1 healthy,1 evasive, 3 fungal comps – cool for Rax/Greg, but otherwise a filler perk)
Impatient3/Devoted2 (3 Zammy/2 Zaros – from nex gear. The devoted part isn’t great for Slayer but is amazing in pvm if you can get it, impatient is still a decent dps boost for slayer).
Additionally I have two gizmos with Undead/Demon Slayer (1 undead comp/1 ancient component – can get the demon slayer part with dextrous too but rarer instead of 100%) and Scavenging2/Looting (5 Precious) which can be cool for K’ril and Edimmus etc but requires an armour switch.
If you got this far, thanks for reading. 🙂 It’s quite likely that I’ve forgotten/overlooked some things, and I also got carried away a bit but hopefully this helps.
