Here's a new version of the Reckless Dweomer and Wildstrike powers, for those who would prefer a simpler, more 4e-like style for these spells.
Reckless Dweomer - Wild Mage Attack 11
You unleash a kaleidoscopic torrent of arcane energy.
Encounter * Arcane, Implement, and Cold, Fire, Lightning, or Thunder
Standard Action - Area burst 3 within 20 squares
Target: Each creature in burst
Attack: Intelligence vs. Reflex
Hit: roll a d4 to determine the effect:
1 - 3d6 + Intelligence modifier fire damage and ongoing 5 fire damage (save ends).
2 - 3d6 + Intelligence modifier cold damage and the target is immobilized (save ends).
3 - 3d6 + Intelligence modifier lightning damage and the target is dazed (save ends).
4 - 3d6 + Intelligence modifier thunder damage, you slide the target 2 squares and it is knocked prone.
Wildstrike - Wild Mage Attack 20
You surround a creature in an aura of chaotic arcane energy that twists any magic he uses to create unpredictable results.
Daily * Arcane, Implement
Standard Action - Ranged 10
Target: One creature
Attack: Intelligence vs. Will
Hit: Until the end of your next turn, each time the target uses a magical attack power (one from the arcane, divine, elemental, primal, psionic or shadow power sources, or any other power the DM determines to be magical), the target makes an immediate saving throw. On a success, the power works normally. On a failure, roll a d6 to determine what happens:
1 - the spell fizzles. Nothing happens and the action and use of the power are wasted.
2 - the spell backlashes against the caster. Treat the caster as the target or his square as the target square.
3 - the spell hits a random target within range (other than the caster).
4 - the spell is reshaped into a random effect. Randomly choose another power of the same type (at-will, encounter or daily) and level from the same power source, and treat it as if the caster had used that power instead.
5 - the spell lapses in power, inflicting minimum damage.
6 - the spell surges in power, automatically critting, as if the caster rolled a 20 on the die.
Sustain Minor: The wildstrike persists.
