Do Ward and Goad buffs stack?

Yes, they stack.

Ward and Goad stack, Hone and Fortify don't.

Use Hone and/or Fortify if you are also using Armor March on your armored emblem team. Otherwise stack Ward and/or Goad, depending on the team composition.

Invisible buffs stack(Spurs,Drives,Goads,Ward)And Probably Give Hector Ward,cause For me i give the unit the skill that the unit does'nt necessarilly need(I gave my Normal Hector ward since he doe'snt need the extra attack).

They stack. I run my arena core (Effie, Sheena, Zelgius) with Ward Armor, and for PVE I now fit LA! Hector with Armor March.
