When one of the missions of the Princess Kythaela, when facing undead enemies, i've activated a cleric skill "Spirit Guardians". I had disavantage when rolling dices because the enemies are UNLIT.
So when i went to use the item "Ring of the Lightbringers" to LIGHT the enemy, the games just Stucks, crashed and stopped to respond. i Recorded a video and did 2 times to can show.
Same here. Two separate occasions, once in a random encounter, enemy was within 10 of character using the "ring of the lightbringers". Used the ring, clicked the spell, game just stopped combat and could not move. Music continues to play, can still move the mouse and access the main menu but the game itself will not allow you to continue. Same thing OP stated occurred in the first gem tower. Used the ring, game will not continue. Its like your still in combat but the game does not know who to let go next.
May your die roll a 20 at least 50% of the time.
Same. Attempting to sneak up and use the Ring of the Lightbringers to cast Shine on an Ogre in the Goblin cave initiated combat, but the effect did bot apply and the character could no longer move or take any action resulting in my having to reload a save to continue.
