Then they are should me more integrated with rules of world D:OS
Shocked(alternative Stun): All actions taken by the target require 1 additional Action Point to perform.
Less chances to dodge and less mind stability because of lower reaction (-1 willpower).
Frozen: Target gains <magnitude> barrier, that absorbs all damage and cannot act until the barrier is broken or the effect ends.
Fire melt barrier faster than other types of damage. (Ligtning should do almost no damage, but there is no differences between air and lightinig, so act as always). May be use resistances of ice elemental for barrier.
Petrified: Target cannot move or act, and is immune to magic.
And there is also should be no lightning damage, but in ruleset of D:OS petrified should act like earth elemental.
