I have’t tried it out yet, but I’m contemplating using a more BRP style of advancement where characters advance by using skills rather than being awarded Advancement Rolls like experience points. As part of that, I was going to let characters seek out trainers to try and learn heroic abilities after a week of intensive training, and a successful attribute roll (generally whatever attribute is associated with the HA). Robust and Focused would get progressively harder with a bane for every time they’ve already learned that ability.
That seems like a cool idea. I'm just looking for alternative ways to obtain them aside from "story ends" or whatever. Seems like they are a cool way to grow your character but i can also see where they can get out of hand if given to often.
D&D can give out feats every X level, while there is no such level component in Dragonbane.
I thought about a cost system, like symbaroum. Where you would put some of your "adventure checkmarks" aside and instead of rolling to improve an attribute you can "buy" a heroic feat. I'm thinking 10 points would be a decent cost, even if it's one you could buy multiple times (or maybe +5 points for each additional purchase cumulative of the same heroic feat... so 10; 15, 20 etc).
Or maybe lower the target on skills to 16 for your first one, 17 for your 2nd and 18 (per the raw) from there.
