chill spd/sieglinde

Give chill speed on any fast unit it's better on sword units but i don't really think Chill spd is good so don't really think giving chill spd is a good idea.

And from my understanding and from the explanations of others is that when eirika buffs, she can get the buffs as well.

Marth with Driving Falchion, Reciprocal Aid, Chill Speed, Drive C-Slot and Drive Def seal is the ultimate support unit
