Effect & research conditions
Research takes 15 seconds and costs 250 Wood at the Church after Papal Bull has been sent. Near enemy buildings, Sentinels become stronger and Hospitallers become faster. If Wall Guns is active, Sentinels can also receive the building-related benefit near enemy Walls.
Research condition
Maltese; Commerce Age; Church; requires Papal Bull Home City Card; 250 Wood; 15 seconds. Wall Guns extends the Sentinel effect to enemy Walls.
When to research
Complete it before a push that will fight around enemy structures, especially when the Maltese force includes Sentinels or Hospitallers. It offers no stated bonus in open ground away from buildings, so compare the research with immediate production if the next engagement will happen elsewhere.
Building-proximity bonus for Maltese infantry
Crusader Knights is a Commerce Age Maltese technology researched at the Church after sending the Papal Bull Home City Card. It costs 250 Wood and takes 15 seconds. Sentinels become stronger near enemy buildings, especially fortifications, and Hospitallers become faster near enemy buildings. These benefits are conditional; they are not a universal attack or speed bonus.
Approaching a fortified position
The upgrade is relevant when Sentinels or Hospitallers will fight near structures during a push. In open ground the proximity condition may not apply, and the Wood may serve another purpose. If the Wall Guns Home City Card has been sent, the effect also applies to Sentinels near enemy Walls. Check the card and Church requirements before relying on it in an opening.
