Getting More Focus Points (mainly through archetypes)

I've had a player who wanted to do some solo play, roll up a shadow sorcerer.
That is a terrifying class once it gets going.
They use steal shadow, which triggers both dim the light and their blood magic.
Steal and vanish off with the targets shadow, to throttle out of sight. Most of their spells are designed to get the hell out if something goes wrong, and mess with their heads spells like illusionary object (naturally)
Healing, good illusions, stealth, and escapes. Everything a solo character needs. They are planning on going down shadow dancer later. But honestly, I'm not sure it will get them anything, since, they are already burning focus spells a lot, and they can't get more focus points.

**Focus Points from Multiple Sources**
It's possible, especially through archetypes, to gain focus spells and Focus Points from more than one source. If this happens, you have just one focus pool, adding all the Focus Points together to determine the total size of your pool. (Remember that the maximum number of Focus Points a pool can have is 3.) If you have multiple abilities that give you a focus pool, each one adds 1 Focus Point to your pool. For instance, if you were a cleric with the Domain Initiate feat, you would have a pool with 1 Focus Point. Let's say you then took the champion multiclass archetype and the Healing Touch feat. Normally, this feat would give you a focus pool. Since you already have one, it instead increases your existing pool's capacity by 1.
Focus Points are not differentiated by source; you can spend any of your Focus Points on any of your focus spells. Likewise, when you Refocus, you get back a point as long as you follow the guidelines of any abilities that granted you focus spells. Having Focus Points from multiple sources doesn't change the tradition of your spells; if you had both cleric domain spells and druid order spells, your domain spells would remain divine and the order spells primal. This could mean that you need to keep track of a different proficiency and ability modifier with the spell DC and spell attack roll of different focus spells.
- You can only regain one focus point using Refocus. While you can repeatedly regain one Focus Point every time you spend one, any additional bonuses to your focus point pool act as "one time use" spells until you the next day. A requirement for the Refocus action is that you spent at least one focus point since the last time you used the action.
