[DF] Some ideas to make damage dealing casters more effective in DF games

[Kuroshima]

My players complain that casters don't scale well, damage-wise, in Dungeon Fantasy. While the main strength of the GURPS caster is versatility, and utility (Buffing/Debuffing/Battlefield control), damage mages are certainly in genre.

New Advantages

Spell Potency

5/level

Each level of spell potency increases the damage of Spike spells by 1. You can not have more levels of Spell Potency that you have Magery.
New Modifiers
Concentration only: This enhancement is available to Power Investiture, Magery, Demonic Attunement, Deathliness, Elemental Attunement, and Bardic Talent. The bonus granted by this level of the advantage can only be used to compensate for penalties due to having multiple spells on. -50%.
New Perks
These are Magical perks, and thus their number is limited. Check Dungeon Fantasy 11 for more details.

Potent Spell†
Increases your magical potency for a single spike spell, by 1. Must specialize by spell.

Faster Missile†
After creating or enlarging a missile spell, you can throw it as a free action. If you do so, you suffer a -3 penalty to both your missile spell skill and your innate attack skill. Must specialize by spell.

Cast on the run†
This is a leveled perk. At level 1, you can move at half your movement speed (round down) while concentrating in a single spell. At level two, you can move your full move. All movement must be before the actual casting. If you move more than one step while casting the spell, though, you must make a Will+Magery roll, at a penalty equal to the distance moved, or lose concentration and waste the spell. Must specialize by spell.

Designer Notes
The spike spells are regular spells, not missile spells, but they're not resisted. They deal low to moderate damage, and always cost energy. Magical Potency is a Striking ST equivalent for them. As they are not missile spells, they're cast on the same turn as they take effect, require no additional roll to hit, and the target gets no active defense. DR, however, protects normally.
