Temple of the Kings

You summon a mystical temple that manifests as a 20-foot by 20-foot area of magical energy at a point around you. You appear at the top of the Temple steps at the summoning alter, as the walls protect you from the back and on the left and right side. The only way to attack the caster is to enter the Temple and climb the steps. However.  When the Temple is conjured, you can conjure The Mystical Beast of Serket at the entrance to the Temple Steps, a powerful creature with the following stats:
