This article refers to the defence. For the creature, see Sentinel.
For a similar Empire defence, see Stone Knight Shell.
The Sentinel Shell costs 5000 Gold and requires 10 defence parts.
The Sentinel Shell, once constructed, can be activated with a click. Alternatively, it will automatically activated when an enemy comes within a certain distance of it. Once activated, the Shell will open and spawn a Sentinel, an ghostly soldier made of pure gold. After the sentinel spawns, the defence will be destroyed.
- The Sentinel Shell resembles an Egyptian sarcophagus, a coffin usually made for an Egyptian king or noble. Sarcophagi were usually actually several coffins, each inside another, with at least one being made of gold.
