In the 18.104.22.168 update, the possibility to recharge blessings was returned, but they went a little bit too far with Merisiel (at least, maybe with other characters as well) and her ability to recharge any blessings played on her Dexterity check.
Android, Normal difficulty Attack on Sandpoint: when Meri discarded a Blessing of the Gods acquired earlier to explore again in Swallowtail Festival location, the prompt Recharge / Discard appeared. The top card of the blessings deck was Blessing of the Gods as well. The same happened later (on purpose) with Blessing of Erastil used to explore. Again, she could recharge it.
Summary: Merisiel seems to be able (now, with her high-level power) to safely recharge ANY blessing for exploration. It needs testing if it affects also her other checks.
Seelah and Kyra should not be affected, as their power is all about the type of blessing, not the type of check.
