Amulet of the Fish

[Leblanc]

Quick question,

I was playing as R'lyeh and I was using the big sea fungus pretender who is also aquatic. I moved him out of the water with a spell so he could cast the spells that can only be on land and I gave him an amulet of the fish so that he could go on land. Anyway, sometime later I took it off without really thinking about it and nothing at all happened. I put the amulet back on him before I ended the turn because I didnt really want him to die but I was wondering if anyone knew whether or not taking of the amulet once on land will hurt a hero.
