Who to check for

Many conditions check for entity properties like whether the entity is burning etc. In situations like attacks it does matter what entity is checked. For these, conditions can define an optional value

"Check For Player": true 

which is disabled by default. When enabled, the gem wielding player will be checked for this condition, otherwise it is always the "other" entity involved in the activation (so for example the attacking entity or targeted entity)
