Horn Drill (move)

Horn Drill (Japanese: つのドリル Horn Drill) is a one-hit knockout move introduced in Generation I. It was TM07 in Generation I.
==Effect==
===Generation I===
Horn Drill always inflicts exactly 65535 HP damage if it hits. Its accuracy is 30%. Horn Drill will break a if it hits.
Unlike other moves that skip the damage formula, Horn Drill does not bypass type immunities.
Horn Drill will not affect a target whose current stat is greater than the user's current Speed stat.
===Generation II===
Horn Drill inflicts damage equal to the target's current HP. The accuracy of Horn Drill is now calculated using the following formula:
Accuracy = \left( \frac{(Level_{user}-Level_{target}) \times 2 + 76}{256}\right) \times 100\%
If the user is a lower level than the target, the move always fails (Speed no longer has any impact on the success of Horn Drill). If the user is 90 levels or more higher than the target, Horn Drill's accuracy is 100% (even though the formula would produce values over 100% for a difference of 91 or more). 
This formula means that the accuracy starts at approximately 30% (\tfrac{76}{256}) when the Pokémon have the same level, and grows by approximately 0.78% (\tfrac{2}{256}) for every level higher than the target that the user is. This accuracy is affected by and stats.
In the Generation II core series games only, Horn Drill can be countered by for maximum damage if it misses. In Pokémon Stadium 2, Horn Drill cannot be countered by Counter.
===Generation III onwards===
Despite having an accuracy of 30% listed, Horn Drill's chance of hitting a Pokémon is instead calculated using the following formula:
HitChance = (Level_{user}-Level_{target} + 30)\%
This formula means that the accuracy starts at 30% when the Pokémon have the same level, and is 1% more likely to hit for every level the user is higher than the target. If the user is at least 70 levels higher than the target, Horn Drill will always hit. If the user is a lower level than the target, the move always fails.
This chance of hitting is not an accuracy: it is not affected by and stats, nor is it affected by other accuracy modifiers such as , Wide Lens, and . Additionally, Horn Drill cannot hit a semi-invulnerable Pokémon. However, effects that guarantee moves to hit (such as and ) still affect Horn Drill.
Horn Drill can be used as the second move of a Pokémon Contest combination, with the user gaining 2 bonus appeal points if was used in the previous turn. It is also part of a Contest Spectacular combination and will give an extra three appeal points if any of the moves , and was used in the prior turn.
When used in a Max Raid Battle against a Dynamax Pokémon while it is under the effect of a mysterious barrier, Horn Drill will deplete two bars of the barrier's strength. Otherwise, Horn Drill will always fail against Dynamax Pokémon.
Tera Raid bosses are unaffected by Horn Drill.
