OK, so I am thinking about attempting the Fight Caves soon, to get a Fire Cape. However, I'm not sure whether my stats are suitable at the moment.

 

 

 

Here are my current stats.

 

 

At the moment I am working on gettin 85 Melee's, 80 Mage by bursting and 80 Range (and whatever HP level comes with that).

 

 

 

Could I do Fight Caves with those stats, how much would each try cost and which method should I use?

Yes, you could easily do fight caves with those stats. When I had lvl 70 melee stats, and 70 range, I made it to Jad easily using the range method. The hard part is actually beating Jad, getting to him is just a matter of having a good inventory so you don't run out of brews/restores. When I first attempted the fight caves, I made it to Jad with around 5 restores and 2 brews. Now I could do it with half my supplies remaining, due to my higher levels now.

 

 

 

So, yes, you could do fight caves.
