Terrain Effects change the terrain as the game progresses. It alters gameplay quite a lot, usually by restricting movement, or causing players to take forced bits of damage.
There are two types of terrain effects.
Effect Blocks are parts that have special properties caused by bombs. They divide into Electrified, Burning, Frozen and Lava blocks. All blocks are affected, even loose parts which are more dangerous as they can get launched around, hitting and damaging players.
Area Effects are generally something along the lines of a large non solid object that applies something on touch. As of now, the only area effect in the game is Poison Gas. It, however, comes in another form, namely Green Poison Gas.
Burning Blocks[]
Burning blocks are parts that deal 5 damage every time a player touches it or moves on it. This can deal high damage over time if not avoided. There is not yet a player skill that can burn blocks, exception being skills that drop bombs that apply burn onto blocks.
Burning blocks can be created by normal blocks touching lava/lava pillars, or being applied this by other bombs.
Burning blocks are very red, emit a small, red shine and small, fire particles. They can sometimes blend in with other red parts, making them dangerous. As such, players should check if red blocks emit a shine and red particles.
When burning blocks are frozen, they are turned into obsidian, and no longer deal damage.
Electrified Blocks[]
Electrified blocks are parts that deal 5 damage every time a player touches it or moves on it, like the burning blocks.
Electrified blocks are only created by lightning strikes and electric bombs. Electric bombs tend to have a much larger blast radius, so you are generally going to find electric blocks in a large cluster.
They are bright neon or blocks that constantly flash yellow and blue, that emit lightning particles. These are less likely to blend in with other yellow blocks as the lightning particles are blue/purple, and since they are a completely different colour from yellow, they do not blend in.
Frozen Blocks[]
Frozen blocks are parts that have less friction, and players can slide on it. They do not deal damage, and cannot be unanchored or destroyed by bombs while still frozen.
Frozen blocks are created by freezing bombs, meteors, things of this sort. They tend to be in a larger radius as most of the bombs that cause freeze usually have a larger radius. When burning blocks get frozen, they become obsidian.
Frozen blocks are the only effect blocks that are not neon as of now. They are a bright blue colour, and emit a white smoke.
As of v3.10.28 frozen blocks have been made much more slippery. However, Heavyweight negates it.
Lava Blocks[]
Lava blocks act like solid lava, dealing 30 damage on contact. However, they are entirely negated by Fireproof.
Lava blocks are only created by the Earth Bomb when it explodes.
Just like burning blocks, freezing a lava block turns it into obsidian. Lava blocks also fizzle out into regular terrain after a while.
Poison Gas[]
Poison gas is an area effect that has a large radius, and does 10 damage per tick to anyone that goes within its radius.
Poison gas is created by poison bombs, like Plagues and Toxic Strikes.
Poison gas looks like a large, purple/green transparent square. It looks very cloudy. It is not neon, and does not glow. It used to look like a large cloud of particles, but that was changed due to it being very difficult to tell the edges of the poison gas.
Poison gas cannot be removed in any way other than waiting for it to dissipate. However, tornado explosions such as the ones from Tornado Bombs and Wind Zombombs can shrink it. Due to poison gas reaching fairly high into the sky, it is a very dangerous threat towards Wing users, as a single touch would break their Wings and deal a fair amount of damage to them. It is even more dangerous to people who use the Aurora Wings, as they will be frozen inside the poison and take an absurd amount of damage.
Green Poison Gas[]
Green poison gas is a variant of poison gas that is fully green. It acts nearly identically to regular poison gas, but it does double the damage, clocking in at 20 damage per tick.
Green poison gas is most commonly released by Poison Nukes, though certain supercharged skills can release it too.
Its other mechanics are identical to poison gas.
