I'm playing a Fighter and I wanted to know if there's any way to increase the amount of times I get to pick from the list of Advanced Weapon Training? Right now I get to pick three times (at 9th, 13th and 17th level) but I'd like for a way to pick one or two more times.
In fact, yes.
You can take the Advanced Weapon Training FEAT, starting from lvl 5 and gain 1 weapon training option for a weapon group you already selected. You can only take thie feat once every 5 levels though, so you can get it starting from 5th, then from 10th, 15th and 20th lvl.
Well, you can take the Advanced Weapon Training feat once for every 5 fighter levels you have and you must possess Weapon Training Class feature (fighter 5). You could take another level in something else and would then need to wait until level 6 to qualify.
But yes, otherwise correct.
