In leveling a Draconic destiny I took Blue dragon heritage 3 tiers which is +30% spell power to electric spells. There is also an option for a secondary spell specialty for another +10% per tier. The option to take electric as secondary is available, for up to +20%. Do these abilities stack for a total +50% spell power? If so seems juicy. Anyone have both? This destiny is only for unlocking purposes but I will be getting around to my sorc soon and if these stack they looking very powerful indeed.
