Dojo Platform of the Lucid Mind

The Dojo platform floor is 20ft by 30ft and 2ft in thickness. It is made of shellacked polished cherry wood and inscribed with dragons around the edges. The creators of this platform are unknown lost to the mists of time but the Sarlona Grandmasters are known to employ it to train their assassins.

Activation

When a monk steps on and concentrates visualizing their opponent (spend 1 KI)*, a spirit construct materializes that behaves in the manner of that opponent. 

*Other classes may also activate but requires the spend of 5 units of mental energy, fortitude, and willpower. Spellcasters may spend 5 levels worth of spellslots. Fighters may spend 5 superiority dice, Psionicists may spend 5 psychic energy. (Sorry barbarians and rogues ^_^)

Usage

Opponents of Huge or Gargantuan size may not be summoned. Only the summoner may see and interact with the summoned construct, to everyone else, the monk will appear to be practicing solo.

The summoned spirit construct are ethereal in nature. They will appear and feel solid except at the very edges where there are hints of transparency.  They will have stat blocks that are the equivalent of their 'real' counterparts. They will also be unaware of anything outside of the platform.

Anyone pushed outside of the dojo while activated is automatically defeated and must Save vs. Death.

Deactivation

The summoned opponent will be dispelled when either it is defeated or the user is defeated.

Construction

The effective spell power is DC20 and spell level is 9 for magical interaction purposes.
For siege purposes, the platform has a Threshold** of 10 and 50 hitpoints.
Combat damage from usage does not affect the construction.

**Threshold is the minimum damage needed to surpass to affect the material's hitpoints.
