What's the most expensive skill to level to 99?

Me and some friends are having a dispute about what the more expensive skill to get to 99 is, I say Construction, they say Herblore. What are your thoughts?

 

Prayer?

 

Herblore is only 70m I believe while prayer is 175m. I'm not to sure how much con is so I would have to say Pray.

 

Someone once told me that it costs ~500m to level construction to 99, but I'm not sure how current that number is. My guess would be prayer.

 

I thought you can make money from Herblore.

 

You could if you have ALOT of time on your hands. Otherwise the most logical and easier way of maxing herblore is to make potions in which there is no profit.

 

i'd want to say summoning or prayer for sure lol

 

Summoning isn't in the picture with prayer, con, and herblore. It's 20m max if your looking into getting it quickly.

 

Its prayer... It costs me like 10m 55-70 and that like 600k exp..

 

its herbolore, cost like 300m i think prayer is around 200m..

 

The most expensive skills to 99 are:

1. Prayer
2. Construction
3. Herblore
4. Smithing
5. Summoning

 

This, though I've heard of people being able to get 99 con for 50m

 

I think Prayer then Construction would be the most expensive.

 

It all depends how you do them. I know it cost my friend awhile back 300m for 99 herb.

 

Prayer is number one to level! Most expensive and annoying :/

 

prayer is the most expensive that is for sure well over 150m+.

 

It does depend on how quick you do the skill too.
Fast and you could spend loads on herblore/construction

 

Looks about right to me

 

Prayer is construction is the second most expensive I believe.

 

You CAN make money getting 99 con if you get items correctly and sell some stuff....major hint right there. and, herblore it depends on method. if you make junk potions then hey u dont "lose it"
