Go into your CNS file and add this:

[StateDef 44304]
ctrl = 0
physics = N
velset = 0
sprpriority = -5

[State 44304, Follow]
type = BindToRoot
trigger1 = 1
time = -1
facing = 1
pos = 0,0

[State 44304, Mimic]
type = ChangeAnim
trigger1 = SelfAnimExist(Root,Anim)
value = Root,Anim
elem = Root,AnimElemNo(0)

[State 44304, STSS]
type = StateTypeSet
trigger1 = Root,StateType = S
StateType = S

[State 44304, STSC]
type = StateTypeSet
trigger1 = Root,StateType = C
StateType = C

[State 44304, STSA]
type = StateTypeSet
trigger1 = Root,StateType = A
StateType = A

[State 44304, STSL]
type = StateTypeSet
trigger1 = Root,StateType = L
StateType = L

[State 44304, MTSA]
type = StateTypeSet
trigger1 = Root,MoveType = A
MoveType = A

[State 44304, MTSI]
type = StateTypeSet
trigger1 = Root,MoveType = I
MoveType = I

[State 44304, MTSH]
type = StateTypeSet
trigger1 = Root,MoveType = H
MoveType = H

[State 44304, Hide]
type = AssertSpecial
trigger1 = 1
flag = invisible
flag2 = NoShadow

[State 44304, NHB]
type = NotHitBy
trigger1 = 1
value = , AT
time = -1

[State 44304, HO]
type = HitOverride
trigger1 = 1
attr = SCA, AA,AP,AT
time = -1
stateno = 44305

[StateDef 44305]
ctrl = 0
physics = N
velset = 0
sprpriority = -5

[State 44305, PVS]
type = ParentVarSet
trigger1 = 1
var(20) = GetHitVar(damage)

[State 44305, Revert]
type = ChangeState
trigger1 = 1
value = 44304

Then, put this at the top of StateDef -1:

[State -1, Hide]
type = AssertSpecial
trigger1 = IsHelper(44304)
flag = invisible
flag2 = NoShadow
IgnoreHitPause = 1

[State -1, Reset]
type = SelfState
trigger1 = IsHelper(44304)
trigger1 = StateNo != [44304,44305]
value = 44304
IgnoreHitPause = 1

Note: Make sure none of the controllers below these two can ever be triggered for the armor helper.

Next put these in StateDef -3:

[State -3, ArmorHelper]
type = Helper
trigger1 = !NumHelper(44304)
trigger1 = Alive
name = "Armor"
ID = 44304
StateNo = 44304
KeyCtrl = 1
PauseMoveTime = 2147483647
SuperMoveTime = 2147483647

[State -3, Ow]
type = LifeAdd
trigger1 = var(20) && StateNo != [120,155]
value = -var(20)

[State -3, Reset]
type = VarSet
trigger1 = 1
var(20) = 0

Also this into StateDef -2:

[State -2, HandsOff]
type = NotHitBy
trigger1 = 1
value = SCA
time = -1
IgnoreHitPause = 1
