The hagr (12 feet tall, long-limbed, rolls of fat and muscle, one eye bulging with hate and fury) just took out the Ranger with that tree it was using as a club. It turns that hate-filled eye on the Heavy and the Blessed (who’s dispelling the unholy fog that kept them from coming to the Ranger’s aid).
The hagr flings the tree at them. The Heavy dives and drags the Blessed to the ground, nailing the Defy Danger with DEX and the tree goes smashing overhead. But they hear the hagr bellow and come stomping towards them.
Still on the ground, the Blessed reaches into his sacred pouch and calls on nature’s fury. The forest erupts, ensnaring the hagr with vines and roots and earth, just a few feet away from them. It’s held for the moment, but it’s already tearing free.
The Heavy rolls to his feet, loads his crossbow, and fires. He’s close, and the thing’s restrained, but it’s ripping free and terrifying and this is anything but a sure thing. He rolls Volley. Gets a miss. Oh dear.
The hagr breaks free, swats the crossbow from the Heavy’s hands, and snatches the Heavy by the wrist, hoisting him up and clearly about to use him as a club to smash the Blessed.
I ask them both what they do. The Blessed says he’s rolling to the side and trying to get away. The Heavy is like “I draw my long knife with free hand and stab it in the wrist, the one that’s holding me, so that it drops me.”
Okay, cool! Seems like the Heavy’s move should resolve before the Blessed’s, but how do we resolve it?
(If it matters: the hagr has like 19 HP, 2 armor, and reach; the Heavy deals d10 damage, hand range, no relevant damage-boosting moves.)
Option A The Heavy is attacking the hagr, and the hagr can fight back, so this is Hack & Slash. On a 7+, the hagr drops the Heavy no matter how much damage is dealt; if the Heavy is exposed to attack, it’s something like the hagr booting him with a forceful kick.
Option B Hack and Slash, but on a 7+, the Heavy’s damage roll determines whether the hagr drops the Heavy, and that in turn determines what the hagr’s attack looks like. If the Heavy deals decent damage, the Hagr drops him and then maybe kicks him away. If the Heavy deals only a little damage, the hagr holds tight and maybe uses the Heavy as a club, the Blessed Defying Danger to get out of the way.
Option C The Heavy is trying to get free more than anything, so this is Defy Danger (STR or DEX or even INT). On a 10+, yeah, the Heavy stabs the hagr and cuts himself free, dealing damage cuz the hagr got knifed in the wrist. On a 7-9, we’ve got any number of worse outcomes, hard bargains, or ugly choices to choose from.
Option D As option C, but the 10+ just means the Heavy gets free without dealing damage, but maybe seizing the initiative or giving the Blessed a chance to act.
