Tower

Tower pillars straight up faster than a jump allows: the block is under the player before vanilla physics could have lifted them that high, and the next rise starts with barely a pause. Many versions also overwrite vertical speed, so the climb looks like an elevator rather than a string of jumps.

In BedWars and SkyWars it's a way to take the high ground over an opponent in a second, escape a fight or climb over base defences. On survival and anarchy servers it gets players out of pits and traps. For an honest player a pillar is slow and exposed; the cheat takes all the risk out of it.

• A smooth climb with no steps: the player never lands on each new block
• The pillar rises noticeably faster than a neighbour's pillar built jump by jump
• The player looks ahead or at an opponent while blocks keep appearing underfoot
• Each hop goes higher than a normal jump, with no Jump Boost effect

A Minecraft jump is exact physics: launch speed, gravity, air drag. The anticheat knows where the player should be on every tick after leaving the ground and compares that with the height of each new block and the moment of the next jump. A new jump without landing, a climb faster than the formula, a block underfoot before the player has risen above it — those are Tower's marks.

Jump Boost, knockback, slime blocks and lag all bend the picture, so one odd height is a reason to look closer, not to punish. Weight builds up when pillar after pillar climbs at the same impossible speed.
