I'm putting together a melee Occultist and I can't seem to find a duration on the focus powers. Am I missing something or are you telling me that as soon as I have a +1 Falcata I can just have it be keen forever for 1 mental focus?
The duration is listed in the description of each Focus Power. It varies quite a bit. Since you used Legacy Weapon as an example:
Legacy Weapon (Su): As a standard action, you can expend 1 point of mental focus and touch a weapon to grant it an enhancement bonus. The bonus is equal to 1 + 1 for every 6 occultist levels you possess (to a maximum of +4 at 18th level). Enhancement bonuses gained by this ability stack with those of the weapon, to a maximum of +5. You can also imbue the weapon with any one weapon special ability with an equivalent enhancement bonus less than or equal to your maximum bonus by reducing the granted enhancement bonus by the appropriate amount. The item must have an enhancement bonus of at least +1 (from the item itself or from legacy weapon) to gain a weapon special ability. In either case, these bonuses last for 1 minute.
Ah, my apparent inability to read the entirety of a paragraph strikes again. Figured I was just being blind again. Thanks for the bolding, haha.
You're welcome. :)
Focus powers have a lot of verbiage to sort through, and there are sooooo many of them. I eventually gave up on flipping back and forth between pages and re-reading those long paragraphs. I found it much easier to organize the focus powers with a bunch of spreadsheets. It's especially useful when trying to figure out the Mental Focus costs.
