A player is affected until the start of their next turn.
If a hero is located on the diagonal space of the Explosion center of an Ice Bomb, will the hero remove 2 side skill tiles?
Yes if it is diagonal you would lose two tiles
When a teleporter explodes, will the teleporter token be removed after the explosion?
Yes, it is destroyed, so it is removed.
When a teleporter explodes, does it actually explode (destroy walls in a Radius of 1 Field, push away players, etc.)?
Yes.
When I step onto a Teleporter and roll (Q), the Teleporter explodes and I go nowhere. Does my movement still end like if I would have teleported?
Yes
Q-Bomb: Can you place a bomb to your right and have it fire forward/backwards or does it have to fire directly away from you? Can you place it beside you and have it hit you?
Bombs fire from the position of your Hero, outward in an orthogonal direction (not diagonal).
If a hero (e.g. Ember) explodes using his ability, does he stay where he is or does he need to respawn?
Hero explosions are focused on the exploding hero, effectively catapulting them straight up. Hence, they stay in place after the explosion. No they don’t respawn.
If bombs haven’t hit anything, during the end of round cleanup phase do you move them in a straight direction the number of spaces on the die or just one space?
They move the distance that appears on top of the bomb die.
If a bomb explodes one space away, diagonally, from my hero, where does my hero jump backwards away from the explosion? Can it jump diagonally?
In the rules is states that heroes (and crystals and sheep, etc) move DIRECTLY AWAY from the center of the explosion. This includes diagonally.
If a bomb destroys a wall on which a hero stands, which direction is he pushed?
If a bomb collides directly with a hero, first the hero jumps directly away from the bombs position (a jump of 1 is actually two spaces), then the explosion is centered on the space the hero occupied before jumping. In this case a wall. That wall, and any wall or player-placed tokens withing one space (including diagonally) are destroyed and any other heroes in that range also jump directly away from the center of the bomb as a Jump of 1.
