1) Touch the rune shaped like a flame (Wrong choice)
The rune flares angrily. Your hand burns with searing heat, and you are thrown back, barely conscious. The forest rejects you. Perhaps you should consider this a blessing in disguise... @Yawhe
2) Speak your full name aloud (Correct choice. Congrats, Bella!)
The runes glow brighter, then fade gently into the bark. A warm breeze circles you—acceptance. The magic of the tree flows into you. You have received the blessing! @BellaTheCow
3) Strike the tree with your staff (Wrong choice.)
A deep rumble answers. Roots burst from the ground, wrapping around you like iron vines. The tree does not tolerate violence. You have essentially become fertilizer for the tree... @Lunes
