Drain

Drain is a HP drain weapon special. It is the second lowest tier of HP drain specials (2★). Drain weapons siphon HP from their targets.

Damage

In addition to the siphoned HP, Drain weapon special attacks deal 0.67x the damage of a normal attack.

Rarity	Special Name	Power
2★	Drain	9%

HP drain specials cannot drain more than a certain amount of HP from their targets, depending on the difficulty level (denoted by Difficulty Cap in the formula below). The formula min means that the lesser of two values (separated by ",") will be chosen.

Base HP Drain = min((Power) * (Enemy HP), (Difficulty Cap))
HP Drained = (Base HP Drain) * (1 - Special Reduction)

• Androids receive a 30% boost to the amount of HP stolen with any of these specials on Ultimate difficulty. This value can be added directly to the value in the Power column.
• Difficulty Cap is as follows:
  • 30 for Normal
  • 60 for Hard
  • 90 for Very Hard
  • 120 for Ultimate
• Special Reduction is as follows (See also: List of weapons with reduced specials):
  • 0.5 for Swords, Daggers, Partisans
  • 0.67 for Slicers, Mechguns, Shots
  • 0 for unreduced weapons

List of Drain weapons

There are three weapon types that can have specials. Specials on common weapons dropping from Monsters or Item boxes are randomly assigned, but are predetermined on all rare weapons. Specials on ES Weapons can be added with Photon drops.

Common weapons

The chance of obtaining specials on common weapons depends on area and difficulty. When a common weapon drops in an untekked state, there is a chance for it to come with Drain as a special. Drain can also be obtained by tekking up or down a common weapon that drops with the Draw or Fill special. Once a weapon drops in an untekked state, the table below lists the overall chance of it coming with the Drain special (including the ability to tekk up or down from Draw and Fill).
