There is another name/type glitch in the game with the Summon Sea Demon ability. This ability is obtained from the seventh chapter of the Spain (Valencia) Portal.
Summon Sea Demon thumbnail shows up in the game under the movement abilities. It was placed under the same stats and ability name as Silver Tongue, which was acquired by doing missions in Iceland Portal.

* Summon Sea Demon * Defensive 25 146 (Portal info)

 Movement 121 122 (current stats)

When you right click on the image you will receive different name of the ability items_summon_water_guardian.png

So now we have three abilities named Silver Tongue in the game.

Silver Tongue Offensive 105 55 (Elders)

Silver Tongue Movement 121 122 (Iceland Portal:Kopavogur (Chapter 1) )
