Vampire labs let you weaken Vampire enemies directly by researching permanent modifiers to their stats. Each lab targets a specific part of how Vampires behave in combat, so their value depends on how much trouble this enemy type gives you.
Description — Vampire Enemy Attack
This lab lowers the attack stat of Vampire enemies by a percentage. It reduces their attack only, not their Drain effect, so their life-stealing behaviour is unaffected. It unlocks at Tier 19 Wave 60 and has 30 levels, with the exact reduction per level shown in the cost table below.

Description
Vampire labs alter the stats of Vampire enemies during rounds. Once you research one of these labs, the base stat relationships between enemies stop holding true. For example, a boss will no longer always have twenty times the health of a basic enemy if you have researched basic enemy health reductions.
