How to use this page
- 1. Treat Lacerta as the first real wall after Rangifer, not as a tutorial rematch.
- 2. If you are stuck here, check the elements, weakness and stagger guide before repeating an under-levelled run.
- 3. The Thunderwave Sword page is the current electric-damage note tied to this fight; it is not a complete Lacerta strategy.
- 4. Do not copy Rangifer’s fire weakness onto Lacerta. That weakness is verified only for Rangifer.
