Sampire with double axe works nice. Run and swing.
If there is big group para balron is easy.
Spawn is high, so healing via running away from paragon several tiles and hitting nearby imp is easy. Or with Momentum strike. Something is usually around.
Tried ninja in tiger form. as
@Pawain suggested. Too low damage output comparing to Sampire.
Parry necro thrower (with healing) works too. Fly, throw, press bandage button, fly away if hit too hard.
all my toons have 0 resist spells now. Tired of being tazed , will squeeze it in some way. All toons have 74-75 fire and physical resist.
