ok so here it is, simple yet effective...
all of my stats are as accurate as possible but may not be 100% correct, also prices will change for planks...
33-74 oak larders (sacred clay hammer) 8 oak planks, 960xp each larder built
For Level 74, you need 1,076,278 XP
Or 687 Penguin Points
You will need to make approximately 1122 oak larders for lv 74 construction which will cost roughly
5.2m if each plank costs less then 580gp each. You will need to buy
8976 oak planks to do this. You will need
420 stealing creation points for the hammers, as you will need 21 hammers each lasting roughly 50k construction xp b4 crumbling to dust.
74-99 oak dungeon doors (sacred clay hammer) 10 oak planks, 1200xp each door built
For Level 99, you need 11,934,431 XP
Or 5,291 Penguin Points
You will need to make approximately 9,946 oak dungeon doors for lv 99 construction which will cost roughly
57m if each plank costs less then 580gp each. You will need to buy
99460 oak planks to do this. You will need roughly
4780 stealing creation points for the hammers as you will need roughly 239 hammers to last for 11.9m's worth xp
A tip that will help you alot is to start assisting construction effigies at lv 88 construction. You can do this by boosting to lv 91 with tea made from a POH (Player Owned House).
By doing this you can assist other players with there construction effigies and make a free 30k xp each day for ur own construction skill! (If 2 effigies are assisted each day)
If you want to do this each day then i suggest going to world 117 on runescape and going to daemenheim centre and look for people who need construction assists there.
Another tip that will help regarding getting the hammers is to play with the clan channel
'Fast Sc' on world 99 as games are non combat, so you can focus on getting points and also finish early, (games usually take between 11-16 minutes), which means more hammers per hour for you without the stress of being killed
Well thats my guide for all you scapers out there I hope that it helps you, also if anything is missing or incorrect please feel free to let me know
You can also private message me in game if you like... at this time my name is 'i h8 sc'
Good Luck Evry1 hope this makes your life a little bit easier to train construction
