Well the annoying thing about truename magic is that each time you make an utterance you need to make a truespeak chec just to be able to do it and it isn't a flat DC. It also didn't have many buffs for its DC against targets making it ineffective and limited. It was also knowledge nightmare to deal with as a player, having to find and know other truenames helping your utterances along while trying to hide yours so you wouldn't be more susceptible. It was cool flavor wise, but if you want to use it eliminate the truespeaking element and apply standard casting buffs/rules you deem appropriate. Since everyone will be using it I am assuming brokenness will be less of an issue.Actually that's the opposite of what I'm going for, it goes against theme, the HP setting has magic on tap and they don't ever seem to run out. That's why I was looking at Recharge Magic.
....Brilliant! Why didn't I think of that! I even have that book I just totally forgot about that system!
If I remember right the DCs were kind of borked resulting in a need for a particular magic item to even out the math, anyone else remember if it had statistical issues to deal with?
