Not 100% sure how this should work:

I have three damaged units and Glittering Tower with Initiate of Saphery in play. When Initiate goes off or I play Greater Heal, does my Tower deal 1 damage, or 3? Thanks in advance for any answers!

3, cf. faq last page.

I think you mean page 14, page 15 is the last page.

And in this case, it's 1 dmg three times, so Toughness 1 is enough to cancel all the damage. Of course since you can, might as well ping in capital for damage in that case.

Or ping a non-toughness unit.

Dwarves shouldn't have any of those out . If not natural Toughness, then Gromril Armor or Mountain Barracks.

Not everyone plays dwarves, you know. I don't think they were mentioned anywhere in the original message...
