Wrap in Flames

With an upward thrust of the hand, flames erupt about the feet of up to 2 targets +1 per every 3 caster levels (Ex. lvl 3, 3 targets, lvl 6, 4 targets ect.) Dealing 1D4 caster level fire damage (Max. 5D4) and rooting the targets in place for one round, dealing 1D4 fire damage at the end of that round.
