Yeah, Wild Talent (Con) has minimal utility, unless your DM has a penchant for calling for Constitution checks.
The Metabolic Control feat would be a better selection for a Constitution boost. Frankly even then, I am not sure Metabolic Control is worth a feat selection, unless you want to raise your odd numbered Constitution attribute and
already had proficiency in Con saves.
The Catnap spell, is not worth the cost of a feat selection, even if the Short Rest effect occurred 10x Faster, and took 1 minute instead of 10 minutes.
Soul Blade, subclassed rogues are going to be great at skill checks. Beyond the Expertise and Reliable Talent class abilities, a Soul Blade can add their Psi Talent die to any ability check that they have the Wild Talent feat for, and if they still fail the check, add their Psi Talent die again through the Psi Bolstered Knack subclass ability.
Jedi don’t need the
Suggestion spell, Obi-Wan was a Soul Blade with Expertise in Deception and Wild Talent (CHA).....”No really, my good Stormtrooper, these are
not the droids you are looking for”.
Psionic builds are going to be very feat intensive. Must be lots of variant humans on Athlas.
