Other easy example....
Staff of the Woodlands Creation: Cost 50,500 gp
For the spells with charge CL=13
9100=400x7xCL/4 Animate plants
7800=300x6xCL/3 Summon nature's ally VI (3 charges)
4333=200x5xCL/3 Wall of thorns (3 charges)
2600=200x2xCL/2 Barkskin
2600=200x1xCL Charm animal
2600=200x1xCL Speak with animals
=29033
For the Spell Effect : pass without trace at will
=2000x13=26000 or 13000(50% similar) or 2000?
For the master staff +2
2x(2x2)x2000=16000
=16000
Add weapon master craft =300x2
=600
Abilities such as an attack roll bonus or saving throw bonus and a spell-like function are not similar, and their values are simply added together to determine the cost.For items that take up a space on a character's body, each additional power not only has no discount but instead has a 50% increase in price.
=71633 or 60633 or 47633
Nop 50,500 gp = (In the best case we have a hole of 2867 gp)
