I think buying proficiency points is a decent route to explore.
RP proficiencies could affect spells since they currently don’t. @Erelei is more than talented enough to code a RO edge proficiency for spells to increase their effectiveness within reason. Adding a value equal to the RP cost and keeping it under game breaking won’t be too difficult. Limit it to one spell per character and you won’t have too much bitching.
Make it class specific and you limit it further. So, no dispel magic, no sleep, no plague, etc.
Invokers could gain a higher chance tk flameblind off firestorm.
Battlemages could see a minimum of CAP damage for sharpmetal.(since it’s weak af)
Shamans could get a +2 for deteriorate.
Clerics could get isolate upped to be an actual effective spell.
Then you could have the hybrids gain something.
DK get an extra 4 hours in unholy strength.
Paladin gain an additional plus to hit/dam.
RP SHOULD affect PK. This game is all about RP and offering these selections allows a person to work towards character development. Mages shouldn’t be excluded.
I see much of FL like I see anime and I think a lot of us do too. Character advancement means power and that’s cool.
