Hey, I've saved up a large amount  of renown and am planning on spending it on large lamps. However, I'm not sure if it would be more efficient to spend it on divination (76) or fishing (86). My goal is to max... Eventually haha.

 

Thanks.

Apparently world event lamps used on Divination have an xp boost. Wiki lists the following:

 

95% xp (of a huge prismatic lamp) normally

109.25% xp on Divination (15% boost)

 

So you have the choice:

.95 * 41.196 = 39136,2 xp or

1.0925 * 26.716 = 29187,23 xp

 

Fishing is probably over 80k p/h at that level, using c2 fishing and SC, maybe more (not sure how much SC boosts). You can also train Woodcutting simultaneously, which further boosts efficiency.

Divination is a good bit slower, maybe 60k xp/h? You also get Hunter xp, which can be quite handy.

 

I don't know for sure which one is going to be better, but I'd tend to say Divination, because Fishing is a great deal faster at any level, and Woodcutting xp is more valuable than Hunter xp.

That makes sense to me, thanks for the help! I might try and level divination a bit more before using the lamps.

While using on Divination can save a good deal of time and some may not like fishing, I'd reccomend using them on one of your expensive buyable skills. 96 Prayer and 89 Con, Two very expensive skills to train - They may be fast XP/Hour but factor in the cash it takes and the amount you'd save using on those instead.

 

I'd be more inclined to say Divination if you were 90+ since at that point the huge lamp saves almost an hour of training per each lamp used but it just wouldn't make sense at 76.

Construction isn't that expensive - it's about 11-12 gp/xp with oak/teak planks, or about 20 gp/xp with mahogany. It's very easy to get free xp with god statues (prayer and construction, as it happens), and you can always get tons of free xp from challenges. Prayer is quite costly with frost dragon bones, but a lot less with dragon/airut bones.

 

If you have a skill that's 240k xp/h and 10 gp/xp, that's equivalent to a skill of 120k xp/h at an income of 2.4m gp/h, or 80k xp/h at an income of 1.2m gp/h. That is, you save an hour at a cost of 2.4m or you save two hours at the same cost. 1.2m gp/h is really pretty low, 2.4m gp/h already very manageable at medium stats, if you make money off Ports and bossing you'll be way over 3m/h. That means Divination is pretty much always a better thing to lamp than a buyable (unless you're a skiller without Ports/MTK/merchanting).
