The sword holds fast; it's wedged in there tight, and it feels like the tree has grown around the blade. She could keep pulling; if she gets just the right angle, she might be able to free it... or, the wood itself doesn't look that tough. She might be able to rip it apart, and get at the sword that way...<br/><br/>((She can take 20 on the Str check, but she'll be fatigued when it's done (about 2-5 minutes), or she can try to tear the tree apart, damaging the tree, and taking a bit longer (about 10-15 minutes).))<br/><br/>In addition, she might notice a very faint whisper, in the back of her mind, when she took a hold of the sword; barely more than the wind, blowing across the open field. She need to make a DC 11 Will save, or be compelled to obtain the sword, any way possible.
