Since the modificaton to giant slayer it appears to be not working properly in fire knight's castle - at least for coldheart who is the only champ i have with giant slayer. Her 4 hit skill is sometimes only removing 1 to 3 shields not 4. When this happens you can see the 4 shields come off and then 1 or two immediately come back on. Eg shield at 8 drops to 4 after skill used and then instantly goes back to 6. I believe this happens when giant slayer triggers. It is adding shields back on. The bug does not seem to exist for warmaster.
