Hi.
"Each round, the target must save or deal 1d8 points of damage + its Strength modifier to itself using an item held in its hand or with unarmed attacks."
Editors note:
If I make my saving throw against terrible remorse, do I become paralyzed for the duration of the spell?
No. The spell is a bit unclear here. When you are targeted by terrible remorse you do not make a saving throw until your turn. On your turn, you must make a Will saving throw. If you make the saving throw, you are frozen with sorrow and can take no actions, but this causes the spell to end. If you fail the saving throw, you deal damage to yourself, but can otherwise act normally.
So is does attacking yourself consume your standard action?
Maybe, i am not sure, i think it needs clarification.
EDIT:First of all check the errated version of the spell (it's not in the d20pfsrd yet) here, so i would have to say that it consumes your standard action. Just compare the spell to the hold person spell (which is one level lower), in the hold person spell if you fail the save you are paralyzed and roll every round to shake it off and if you make the save nothing happens to you, now in the terrible remorse if you fail the save you lose your standard action and roll every round to shake it off and if you make your save you are staggered for 1 round.
It seems ok to me.
