Beast of Reincarnation Thunderwave Sword: Lacerta Guide
Thunderwave Sword is useful as an example of how to match a Beast of Reincarnation weapon to a boss weakness. A Steam Community achievement guide identifies Lacerta as weak to electricity and names Thunderwave Sword and Bolt Shards as electric options. The guide does not publish a complete stat table or a guaranteed drop location for the sword.

How to use this Beast of Reincarnation weapon note
- 1.Confirm the target is Lacerta before copying the electric setup; the source note is encounter-specific.
- 2.Equip Thunderwave Sword if it is already in your inventory, or use the named Bolt Shards alternative when a ranged approach is safer.
- 3.Keep the visible weakness and your own damage result as the test: the Steam guide does not provide a fixed multiplier to reproduce.
- 4.Use parries to create openings rather than standing at range for the whole fight; the rest of the combat loop still depends on Emma and Koo working together.
- 5.If electricity is not producing the expected result after a patch or difficulty change, record the version instead of treating the old guide note as permanent balance data.
Evidence boundary
The source describes Lacerta as a boss whose jaw and tail combinations can be parried and recommends attacking during the pause after those combinations. Those encounter observations remain player-reported; this page does not present them as developer-published frame data.
