I was ironically thinking of a class replacement called Rune Knight for the past few month, or at least creating a spell for the WaM called Runic Blade, in honor of the FF5 class, altered to fit more into this game.
Runic Blade
By spending a round to cast this spell, the WaM/RK enchants his/her blade with an arcane spell, increasing the final damage s/he can do to his/her opponent. The number of ranks of the spell can neither surpass Runic blade or the Arcana spell. (Ex: if the warrior has 3 ranks of Runic Blade, but 10 ranks of Flame Bolt, the blade can only do three more points of damage. Likewise, if the caster has 7 ranks of Runic Blade, but only two of Ice shards, the weapon can only do two more points of damage).
It takes concentration to maintain the spell, so every round costs the same amount of stamina as it would to cast the spell, hit or miss. The damage is calculated post-damage roll, so an attack that has the fore-mention flame Bold would do 3 more points of damage. However, if the roll does not connect, then the stamina is wasted. (EX: if you need a 66 to hit and roll a 64, you do not add the 3 from the Flame Bolt to your attack roll and you miss). If you use the !evade ability to restore your stamina, then the spell dissapaites, and you have to spend another round casting it once again.
