In Multi-player mode, select Spire and play on any arena. When the battle begins, switch to your alternate form (Dialanche) and go to any vertical wall. Note: Inwardly-sloped walls, as in VDO Gateway, cannot be climbed. Roll at the wall to start climbing the wall. However, you can't stick to ceilings. If you exit alternate form, you will fall down. Note: The best arena to practice wall climbing is Combat Hall.
