Dryads trust you to bear their power and their bond.
Benefit(s): You can cast meld into stone as a spell-like ability once per day with a caster level equal to your character level, except that you instead meld with wood. You can remain melded with the wood for up to 24 hours. If you meld with a dryad’s bonded tree, the dryad can treat you as her bonded tree for a number of days equal to your Charisma modifier (minimum 1) after you leave it; the dryad retains her bond to her tree during this time as well.
