The Fortune Blessed

[Amnoriath]

It has a couple of interesting features however there are a couple of obvious issues here that call into question of its balance.
Good
1. Twist the Fate and Ask the dice. I really like these abilities flavorful and useful without being an upfront success.
2. Right tool for the job, one could always use some single use stuff. However, better worry about custom item rules.
3. You have some decent ways to keep rerolls.
Bad
1. Fortunate soul is asking for nasty numbers in all departments. When a single prestige class can simultaneously replicate about 10 spells at the same time that can still stack he isn't simply lucky any more he becomes good at every thing.
2. Gambler's edge, you effectively rendered useless the luck feats while directing them towards your auto-success abilities. Also see 1
3. Luck Favors the Bold, auto-success, see 2. Possibly auto-vorpal with the right feats
4. Lucky Break, 6 free miracle-like abilities a day as well as 1 every 30 seconds one level before Clerics and Wizards get one. That is a problem.
5. I understand to a point you are expecting lucky characters but most entering this won't get to use their feats to help their strategy which really hurts the feat starved tier 4's or some 3's in play.
