This is just my Slayer Journal. And a place to keep notes on what to take when fighting. This was a list of all the slayer assignments I received, but it was getting a bit long. Now it's just notes on what to take when fighting.
164 Black Demons - Get a dragon halberd. take an anti-dragonfire shield when getting there in case a blue dragon gets on your case. There is a place where you can safe spot the demons with the halberd. Take a gem bag and an herb bag.
34 Iron Dragons - Equip the best ranged armour you have, rune crossbow ava's accumulator, and the trick is to use emerald bolts (e). In inventory take coins, an axe, a few each of anti fire potions and
ranging potions. Just maintain your distance from the dragons and you'll do fine. I would imagine this would work with steel dragons as well.
166 Kalphites - Take a rope is about all.
139 Infernal Mages - Best magic defence armor. They don't drop much, so you can bring plenty of food. take coins, combat potion, maybe 2 empty spaces and lobs for the rest
164 Banshees - No food needed, they drop a lot of herbs, so if you have an herb sack, bring it along
150 Trolls - Melee equipment and maybe 5 free spaces, herb sack and gem bag
146 Blue Dragons - Ranging them. When doing melee, take super attack and strength and 10 lobs
14 Wall Beasts - don't forget a light source and a rope
154 Basilisks - In inventory take coins, dramen staff, fire staff and natures for alching. Maybe 2 or 3 lobs, just in case. Best Melee armor and a mirror shield. Herb sack if you have one
18 Steel Dragons - I'm going to go after these like I did the Iron Dragons
149 Lizards - wear desert robes & melee armour. Take waterskins, a knife and Ice Coolers. They drop plenty of kebabs so food isn't a worry.
145 Elves - had to do Roving Elves quest and start Morning's End Part 1. No big deal after that
14 Mutated Zygomites - Bring Fungicide and wear dragon hide armor
48 Molanisks - Bring a slayer bell, dramen staff, light source and melee equipment, herb sack
151 Turoth - Leaf bladed battle axe, melee equipment, some food
162 Cockatrice - Mirror shield, take 2 tuna
143 Jellies - Magic based melee, so wear dragonhide armour. bring runes for alching. bring plenty of food, these don't drop much
169 Fire Giants - able to safespot them to work ranged - if doing melee, bring a full inventory of lobs, bring herb sack and gem bag
124 Pyre Fiends - magic based melee attack, so wear dragonhide, take 5 or 6 lobs, you can also mage them, take double the lobs if you do
Cave Crawlers - Bring a herb sack for the drops and some anti-poison, their poison hits fairly high
Rock Slugs - Bring bags of salt and a coal bag to extend your stay
Greater Demons - Range them in Brimhaven Dungeon, take the gem bag and runes for alching
Hell Hounds - Kind of lame. Range them in Taverly Dungeon
Spitting Wyvern - Just Melee, take super attack and super strength and about a dozen high food, lobs or better
Jungle Horror - Melee. Take a little food is all
Fever Spiders - Slayer Gloves required, maybe a little low level food
Aberrant Spectre - Dragonhide armour, herb sack, attack and strength pots, fill inventory with lobs
Spiritual Creatures - Have to go to the God Wars Dungeon for this. Take Zamorak Mitre, Blessed Symbol, Bandos Cloak. With those 3 pretty much nothing will be aggressive. Take Super attack, strength, and restore potions. Best melee armour, and a one click teleport out. Fill inventory with food. Take runes for alching
Skeletal Wyvern - Tank them. Super attack and Strength pots is all. Take lots of good food
