I had an Orb of Warding in play and my opponent cast 2 1/1 human soldier tokens that attacked me. I lost 2 HP when hit for 2 with orbs in play. Two turns later my opponent cast 2 more of the same token, making a 4/4, and I was hit for 2 HP when it attacked. I took a couple screen shots, and will try to get some video later, but I thought I would go ahead and post here.
Orbs of warding is the only support in play, I was able to get a screenshot showing the damage counter (-2) and that it did infact deal 2 damage to my PW. Screenshots times are 8:57:17, 8:57:21, 8:57:32 respectively.
So based on first post you say that a 2/2 hits for 2 and a 4/4 also hits for 2.
It could be some problem related to the game not allowing 0 damage(for whatever reason) so in that case the reduction won’t work.
That’s my best bet for the reason behind it.
Anyways it is obviously a bug.
After some further testing with this deck. It seems that I only take the non-reduced damage the first turn that I am hit after playing the Orbs. I have yet to play it with multiple creatures in play for my opponent to see if it only skips the first hit or the first turn.
Just tested with an opponent that had two creatures in play when I played the Orbs. The first creature deals normal damage the second deals the reduced damage.
I noticed this bug as well. I use this card a lot and can tell you, the first hit you take after playing orbs of warding, you will always take full damage. Theres also a bug with it that when hit by a creature with lifelink, the creatures controller will always get the non reduced amount of life back, no matter how many hits you take. Because the damage reduction wording, its a replacement effect, and should grant less life when dealing damage. So if a 4/4 lifelink is hitting you, you’ll take 2 damage but they’ll still get 4 life.
