XP RATES AND PRICE PER XP:
There are different levels of monsters you can reanimate but for the purposes of this guide I will be using Bloodvelds as they are fairly cheap but still great XP.
Bloodveld XP per hour: ~230k
Bloodveld GP per XP: 6.8 (Including all runes, heads, and other supplies)
Compare those with Dragon Bones:
Dragon Bones XP per hour: 330k
Dragon Bones GP per XP: 13.8
So Dragon bones are exactly twice as expensive and only 100k more XP per hour. You also gain quite a bit of combat and magic XP while doing this.
Step 1: Gain access to and use the Necromancy Spellbook:
1) You must gain 60% favor in the Arceus House in Zeah to use the spellbook. Follow this guide but remember that you do not need 100% you only need 60%:

2) After you get 60%, talk to Tyss who is located near the Dark Altar which is in North Zeah (look on your map) and he will switch your spellbook over to Necromancy.
Step 2: Finish Required Quests
1) Fairytale I: No skills or other quests needed to finish this it's simple and quick
2) Fairytale II: YOU ONLY NEED TO DO PART OF THIS QUEST. You do not need any of the skills requirements needed to get to the part of the quest that you need completed. Once you gain access to the Fairy Rings you are done. The fairy rings are all you need from this.
Step 3: Pay to use the Zeah Fairy Ring
1) After you gain access to the fairy rings, you must go to the location I link below and pay the NPC 80k, you will then have access to use the Fairy Ring:

Step 4: Buy Supplies and start training:
1) The supplies you will need are:
- Bloodveld Heads
- Nature Runes
- Soul Runes
- Blood Runes
- Law Runes
- Dueling Rings
- Melee/Range gear
- Super strength/attack/range (Optional)
- Rune Pouch (Optional)
2) Below is a guide to train, the only difference is you don't need to use a cannon and you also can just tele to clan wars after you're done with an inventory to regain Prayer/Health at white portal:

At 25 defense I did not need to bring any food and rarely ever fall below 60 HP. Post if you have any questions
