Preservation Chance

The preservation chance is a modifier which lets us preserve the resources used when creating items. As a return, we will be able to make more items, entirely for free!

Note that the preservation change does NOT affect the usage of potions nor summoning tablets.

The preserve chance is capped at 80%, and is additive, regardless of source.

Obstacles

Obstacle	Pillar (most effective → least effective)
III	Pipe Balance
IV	Coal Stones
VI	Tree Hop
VIII	Runic Trail
IX	Ice Jump
X	Lava Waterfall Dodge
XII	Rune Crawl	Cave Waters
XIII	Cave Trap
XV	Lava Trail

Runic Trail mostly affects Summoning stuff, and should NOT be used when doing Herblore.

Cave Waters affects Potion charges. Do NOT use it in Herblore. Similarly, Rune Crawl spares your tablets, but is bad for potion consumption. Tradeoff.

Cave Trap is actually BAD for resource usage, but will spare you potions and summoning tablets.

Obstacles but combat

Obstacle	Pillar (most effective → least effective)
IV	Cave Climb
VI	Tree Hop	Lake Swim
VIII	Runic Trail
IX	Cave Maze
X	Lava Waterfall Dodge
XII	Rune Crawl	Cave Waters

Ammo and rune preservation. Also Prayer stuff. Read notes specified above regarding tradeoffs.
