i think it is 4 exp per 1 damage (10 now days damage).
Fire giants are level 85 in Runescape 3. They grant 424.8 experience points per kill.
At your level, I would say killing Experiments ( Level 25 - 100Hp = 400exp per kill ) near Canfis.
250xp per log
all you can really do is just train on rock crabs(200xp per kill) experiments(400xp per kill)
IvyIf you mean in Runescape, for non-members that would be willow or oak. Yew gives more experience per log, but it is very slow.
For lower levelled players, consider doing slayer until the point they can kill blue dragons. For medium level players, consider 85 Dungeoneering for Frost Dragons. For high level players, the Kalphite King and Nex would provide a bit of end game PvM. All of these would give a nice amount of experience and gp per kill.
depends on you're experience rate per hour e.g [45k per hour] and how many hours you train a day.
By fishing. Once you have the level, fish at the Barbarian Village. More advanced fish gives you more experience per unit, but it is slower to catch each fish.
Casting high alchemy can grant up to 78,000 magic experience per hour if casted efficiently.
Sell something worth 1M every hour. Or simply mine, woodcut, skilling, kill Giants, stew making or crafting.
You need 40,000 Dungeoneering tokens, so you need to get about 400,000 Dungeoneering experience. I couldn't find any reference on how much experience you typically get per hour, and I don't have enough experience myself yet.
There is no way to get money that fast in RuneScape.
