First sentence correctly specifies a conditions that agent must met to be able to move to any version of hero Haven.CRF, Rulings by Term, Agents wrote:Agents may not move to any version of a hero Haven, unless they have a special
ability allowing them to.
[...]
Only Elven agents can move to a site that is a Wizardhaven.
Sense of second sentence should be reconstructed because literally it has no impact on game at all. Hero and FW players use hero site cards for hazard agents, minion players use minion site cards for hazard agents. None of the site cards is Wizardhaven; other versions of them may be Wizardhaven.
Except the fact that coincidentally all currently released Elven agents have a special ability allowing them to move to a Haven, the race of agent has nothing to do with the ability.
Additionally one issue is not regulated. Versions of which Wizardhavens should be taken into account? These for which Wizardhaven site card has been released, the sites for which version currently in play is Wizardhaven, or both.
I propose the following erratum for the second sentence:
"Only agents that have a special ability that allow them to move to a Haven can move to a site for which version currently in play is Wizardhaven."
