Idea I've been tossing around, for those that still want skill specialization and are willing to put in the neccessary bookkeeping:
New Cosmic Ability
Hyperfocused
Requirement: Int 80
Benefit: Your total skill points available become HD x (10 + your Intelligence modifier (not including any non-permanent modifiers to your Intelligence)), superceding any other method of calculating skill points. Additionally, the cap of allocating skill points is removed, allowing you to allocate as many points as you wish to a single skill.
Special: As you no longer have a skill point maximum, Maven (and similar abilities) no longer have any effect on you.
This one seems like it could potentially get a little wild, so worth posting it on its own.
I would be very careful with that. That can get way out of hand very quickly. Skills have certain exploitation loops that if aren't checked can have disastrous consequences for your campaign.
I have a lot of skill monkey types in my campaign, so I actually made a list of abilities that both makes them stronger and also reigns it in a bit. I based it off of powers of equivalent level and by increasing the power of the "Epic Skill Focus" Feat appropriately.
I don't mind players eventually getting to the point that, just like attack bonus, saves or ac, they simply can't be resisted on a certain skill, but I make it, just like those other abilities, a Transcendental Ability.
Enjoy.
