Wall of Ytilibicnivni Laciritas

When this spell is cast, the caster creates a 5 foot radius sphere around them. In this wall, no spells can be cast on the inside nor outside to deal damage or heal, it cannot be entered or exited, and the caster must use their action to maintain concentration. This sphere cannot be moved from its point of origin unless that point is already in motion. If cast by a PC during combat, if the remainder the party is killed [via TPK] the effects of the spell ends and the caster is killed outright.
