...how would you characterise dominate person cast with indefinite duration?..
...upcasting dominate person at eighth level can maintain up to eight hours with concentration, so i'd be inclined to consider twenty-four hours duration equivalent to a ninth-level spell, but perhaps i'm under-gauging the difference in power between eighth and ninth-level spells?..
...regardless, in this particular case it was cast with indefinite duration plus disadvantage on the saving throw against a hostile player character, which i'd like to translate into mechanical terms: maybe a ninth-level casting with heightened metamagic plus silvery barbs?..
...i'm playing with a DM who has a poor grasp of fifth-edition's mechanical balance and i'd like to help him understand just how adversarial his homebrew and houserule tendencies are leaning, especially for early tier-two gameplay...
...seven months in this case, but the remaining party found her last night and it looks like she might finally have an opportunity to escape next week...
...we've been playing together since the holmes set in elementary school so i've stuck with the campaign as a gesture of goodwill; our DM means well but i've let him know that the campaign's a poor fit for the character and she intends to leave at an appropriate narrative moment...
