I'm not going to worry about the Tutorial dungeon or the Mirror enemies, mostly because they're optional. I looked at the Mirror enemy Story file and I believe that the Mirror for the default Player 2 template will spawn and have no usable skills.

I have updated the WIP version of the mod so that the single Source Hunter receives the following when they arrive at the Cyseal Beach-
Code
6 Attribute Points
5 Ability Points
2 Talent Points
The Lone Wolf talent if they don't already have it, or 1 extra Talent point if they do

I'm adding these after character creation because I don't want to mess with the strict point requirements that the properties.lsx has for that process. If you don't pick Lone Wolf at creation and receive it when arriving on the beach, you'll get a message saying your partner has left the party; whether this means something goes to the Inn, I don't know. You'll also start with a chunk of your health missing, since it doesn't heal after forcing the Lone Wolf bonus on your character.

At the very least, I believe having the forced Lone Wolf talent combined with the single Source Hunter will mean that companions won't be recruitable at all (meaning it's a true Solo experience).

The updated WIP version link is the same as the one in the opening post-
