Hi everyone! We're pushing a small hotfix today containing a couple of things -- but one of them may be really important for some of you. We'd really appreciate your feedback about one particular change we've made.
So the most important thing in this small patch is:

• We've been looking hard at the issues you've reported with the game's bad performance on high-end PCs - especially the "hiccups" / small, constant framerate drops / lack of smoothness during gameplay. We think we came up with a solution and after today's patch the game should run better - and the "hiccups" shouldn't be noticable anymore.

• It shouldn't be possible to "overwrite" a runestone instead of switching it for another one.
• Legendary cards now properly lose charges again
• Sound effects of buffs and debuffs were tweaked a bit
• Stagfather's charm icon was updated to remove the Warding Lore imposter.
• Oversaturated Stone can't be used and wasted outside of combat.
