Do you gamers open an exception to casting one spell per round, and allow one spell caster to cast as many instantaneous spells as the character can, knowing that each instantaneous spell only costs 10% of the round to cast. Say, a semi-spellcaster fighter, could turn 4 arrows with 40% of activity spent and still attack with 50%. Or he could do even better with AM Speed or Haste.
OPEN MENTALISM LISTS, Attack Avoidance,
8-Aim Untrue I (F*) As Deflect I, except missile automatically misses.
There are more spell lists like this, namely the Beastmaster Combat Enhancement, and the Channeling Shielding Ways.
