You create a beacon in time to return to it if things go wrong. You can cast Маяк времени only on your turn. Keep careful track of everything that happens this turn after you cast Маяк времени. At the end of your turn, you can choose to rewind time back to just after you cast Маяк времени, removing all effects of your turn since then. Curses, traps, and other harmful effects that happen during your turn might prevent you from returning to the beacon if they're powerful enough. If you were affected by any harmful effects during your turn after casting Маяк времени, in order to return to your beacon, Маяк времени attempts a counteract check against each such effect. If it fails at any of these checks, you can't return. After returning to the Маяк времени, the spell ends.
