The methods of leveling mage is mainly cursing and stunning years ago. But today people overlook and view cursing as a thing of the past. Here are reasons for that popular myth.
How to curse?
In order to curse your magic bonus needs to be -65 or lower. So you will need to be wearing plate armor and dragon hide vambraces. The reason you want to have the lowest magic bonus possible is so that the spell will splash every cast. If the spell doesn’t splash, it forces you to switch targets because you can’t cast a curse while a curse is already active on a target.
What is the cost per curse and how much experience does it grant?
The cost per cast is a mere 5gp with a mud-staff. The experience granted is 29. You will gain roughly 30k exp per hour, and lose around 5k per hour.
How does cursing fare against high alching?
Currently, the most popular method is high alching. High alching grants 65 exp per cast and usually around 65k exp per hour. The cost to high alch is around 100gp per cast or 100k gp per hour.
Rough Conclusion: Cursing gives roughly half exp and is 20 times cheaper than high alchemy. Even if you find something to alch that only costs 50gp per cast, you will still lose 10x more.
Sacred Clay Armor: Sacred Clay Armor grants double magic experience when casting combat spells. Cursing and stunning are considered combat spells so if you wear any piece of sacred clay armor while cursing or stunning you will gain double exp.
So if you wear sacred clay, you will gain 58 exp per curse and 180 exp per stun.
Roughly speaking, you will get 58k exp per hour cursing and 180k exp per hour stunning. Compare this to high alching which is 65k exp per hour. It is worth saying that a stun will cost around 200gp per cast.
Conclusion: If using clay armor, cursing is way cheaper and almost gives the same exp as high alching. If stunning with sacred clay armor you get triple the cost but also triple the exp! So stunning with sacred clay is identical to high alching except it’s three times the speed.
