Custom Magic Items

[Nerdynick]

So, what are your thoughts on allowing custom magic items built off the table on page 550 of the CRB? I'm very hesitant to allow players to build a Use-activated magic item that allows them to cast Cure Light Wounds at CL 1 at will for 2000 gold. I've read threads before debating if its heresy to allow arcanists healing magic or divine casters powerful blasting magic, but is it destructive to the game to allow every character to ensure that they're at full health after every battle?

As a further example of how these rules might be exploited, you could build a similar item for 2000 gold that casts True Strike at will. These items, created by the rules presented, seem really out of line with the power level of items of similar cost.

Something that is also often said that these are guidelines, rather ten strict rules. DM are advised to change prices to fit with excising items.

Like True Strike for example, the book (http://www.d20pfsrd.com/magic-items#TOC-Magic-Item-Gold-Piece-Values) it self even says:

Example: Rob's cleric wants to create a heavy mace with a continuous true strike ability, granting its wielder a +20 insight bonus on attack rolls. The formula for a continuous spell effect is spell level × caster level × 2,000 gp, for a total of 2,000 gp (spell level 1, caster level 1). Jessica, the GM, points out that a +5 enhancement bonus on a weapon costs 50,000 gp, and the +20 bonus from true strike is much better than the +5 bonus from standard weapon enhancement, and suggests a price of 200,000 gp for the mace. Rob agrees that using the formula in this way is unreasonable and decides to craft a +1 heavy mace using the standard weapon pricing rules instead.

Just compare and contrast to exiting items and change the price or uses of the item as you as a DM see fit. And to be fair, they are rough guidelines due the magic system having a lot of exceptions due some spells being insane as items and others mediocre, even though both spells are the same level. It will always be a case by case basis if your players want to invent their own magic items.
