Oathguard Keep

Hold both approaches

The upper and lower entrances converge on one keep exit. Lower spawn packets alternate between the shortcut and southern bypass; their roads never switch during travel. The ancient Oathfrost Beacon stands separately in the central snowfield.

Local testing

Nine interactive foundations use normal construction, upgrades, selling and rally controls. Both heroes have independent movement, health, charge and respawn. Prototype tools are separate from the normal campaign. The starting economy is 900 gold with 45-second intermissions and up to 10 gold per early wave call.

Validation boundary

Campaign progression, both hero pairings, heal/freeze, fixed routes and atomic beacon repair and simulator builds are tested locally. Physical-phone performance and final balance require review; see the local campaign validation record for actual tests. New character art estimates total 104 MiB decoded RGBA; compressed WebP size is not a device memory measurement.
