Originium Science Park Level 3 Auto-Defense Guide
- Surge Towers and Beam Towers Are Recommended
- Group Facilities Before Paths Split
- Counter the Pyromancer's Teleport
- Beam Towers Are Effective Against Executioners
Surge Towers and Beam Towers Are Recommended

For this Auto-Defense stage, a mix of Surge Towers and Beam Towers is recommended. You'll need Sandleaf to craft the required Steel Parts, so if you haven't found that material yet, push forward with the main story first.
Place More Facilities on the South Side
The southern section has two routes. If enemies push both lanes simultaneously, your defensive damage will be split. Since it's easier for mobs to break through here compared to the north, stack more defensive facilities in the south to hold the line.
Group Facilities Before Paths Split

Positioning your defenses at convergence points allows you to hit multiple targets simultaneously. For this stage, you should group several Surge Towers on the southern route to wipe out enemies before they have a chance to split up.
Counter the Pyromancer's Teleport
The boss, Bonekrusher Pyromancer, warps forward when taking damage, making it hard to stop with standard LN Towers. A smooth way to handle this is to trigger the teleport with a Surge Tower, then have a Beam Tower waiting at the destination to take it down.
Beam Towers Are Effective Against Executioners

The Bonekrusher Executioner gains a massive Defense buff once its HP drops below 50%. Beam Towers are the ideal counter here, allowing you to burst down its HP quickly before that defensive passive activates.
Originium Science Park Level 3 Operator Intervention Guide
- Place 2 Sets of 4 Surge Towers 1 Beam Tower
- Utilize Solidification Skills
Set of 4 Surge Towers 1 Beam Tower

For Operator Intervention, it's recommended to place 4 Surge Towers and 1 Beam Tower in both the northern and southern routes. The south side is trickier with two invasion routes, so you should keep your characters positioned in the south to handle leaks.
Prioritize Bonekrusher Vanguards

Be especially careful of the Bonekrusher Vanguards appearing in the south. Since they wield shields that mitigate damage, your towers might not kill them in time. Engage them manually near your Surge Towers to focus them down.
Utilize Solidification Skills

You can stall non-boss enemies for a long time by inflicting Solidification. It is particularly effective to lock down the Pyromancers in the south while they are in range of your Surge Towers. If your roster allows, bring a team composition specializing in Solidification.
