The slippery ice tiles will shoot you in a random direction other than the one you are walking/running and/or will teleport you about a meter or two away. .
The slippery ice tile does move the player in unpredictable directions, you are correct. This was the best I could come up with, and I certainly don't deserve the credit behind the idea for the ice tile, either. It has been requested as a Frostfell item ever since the slippy ice region was introduced with the Frostfell Wonderland Village. Unfortunately, the exact mechanics of zone art cannot be transferred to player movable objects. We've been able to fudge some (like climbable ladders!) but a true slide-in-the-direction-you-are-already-moving still eludes us. Even the Tinkerfest conveyer belt is different in that it is pulling you in a direction, according to the object placed, not according to the direction of player travel. It's all scripty trickery! If we do find a way of making a ice tile that functions differently we'll just make a new tile for it at that time. This slippery ice tile will remain as is. ~ Kaitheel
