Well with Sorsha, they are logical pick

And with low lds, they are great unit in high numbers.
On side note, i played with rage spirit files, and got to lina/gizmo. What dmg type is it`s attack ? For ice thorns, you make it physical , for slime there is poison type and physical for fishes. But for gizmo no dmg type ?
And rage spirit skills prevail physical dmg, and fire dmg not at all. Zerroc 3 phy skills, Sleem have 2 poison/1 phy , Lina 2 phy (orb and now ice thorns)/1 magic (i think gizmo is magic type), Death 2 astral, and soul rip i have no idea dmg type.
How about make falling rocks 50% phy/50% fire dmg ? Rocks falling from sky, burn chunks of lava ... ? Quake is pure phy dmg, and it makes sense , but how about making at least 1 rage skill part fire ?
And is there any way to make destroying rock wall and thorns to regain rage ? As it is now there are lots of situations i want to spend rage to get at least some exp for spirits, but without dmging enemy units i keep at bay before finishing battle. So my choices are rock wall/glot armor/frozen orb/time return. Only rage skill I as player can attack are wall and thorns, but as it is now they give absolutely no rage in return (as it is in Ap/CW). Idea is this possible.
