Dilettante vs Intensified spell

[Malik Gyan Daumantas]

Basically which is generally better for a magus.
Now at first glance this seems like a no brainer.

But this is really a question of do i want more in combat power?
or out of combat utility.

This is what dilettante does

Spoiler:

What some would call dabbling you call a wide range of interests. Your breadth of knowledge offers unexpected insights in many situations.

Prerequisites: 2 ranks each in 5 different Knowledge skills.

Benefit: You gain a +2 bonus on Knowledge checks if you have 1–5 ranks in that skill. This bonus does not stack with Skill Focus. You can make untrained Knowledge checks with DCs up to 15.

Normal: You may only make untrained Knowledge checks for common knowledge (DC 10 or lower).

Oh and keep in mind that this is assuming you're taking intensified spell and NOT using the Magical lineage trait for shocking grasp.

Those aren't really comparable options, especially without context (type of campaign, level range, etc.).

In general, I'd go with intensify as it is still worth it for a level 2 slot compared to other touch spells at that spell level.

Cracked Magenta Prism Ioun stone are a cheap +2 to any skill that can be swapped once per day. In general, you shouldn't worry about missing too many knowledge checks as a Magus.

Dilettante seems like something you get pretty limited returns out of at later levels, I'd swap it out past low levels regardless, especially if your party is beyond rank 5 in all the knowledges.

I'd enjoy dilettante, despite its limited effect it's a more character defining ability than intensify spell. But if there are others in the party getting knowledge skills it'd be pointless, and at 8th level+ it'd stop providing a benefit in many cases. From about 10th I'd call it worthless.
