|Examine||I can balance on this.|
Spines are found next to the quills in two patches near the lodestone during the Tuska Comes event. Players may balance on them for Agility experience; balancing on a spine while there is lightning around it will grant the player ten times as much experience than balancing on the other spines. Tuska fragments can also be obtained by doing this. One spine in every patch will have lightning at one time. The spines regrow when the Tuska event is active. After the 20 minute period, they can be removed by a single click, to allow balancing on the remaining stump again.
