I love it when the dice write the story so jumped on the critical hit/fumble deck soon as it came out. Back in 4e I also used the encounter card packs for the same reasons. (this was back when they was trying turn it into magic the gathering...)
I figure if they draw a death card that is why they have hero points... What combination of critical success/failure and the critical hit/fumble deck just wrote its own story?
This is the hellknight hell first level boss so mild spoilers.
So the goblin dog gets a triple max damage crit hit card on the mud drake leaving it sinking into the muck. The muck itself was more dangerous leaving everyone retching as was the goblin pox...
But this card leaves me thinking if the upcoming boss does that it would drop a player....I doubt this arrest can happen.
They climb up with only the halfling cleric taking the fall (the dwarf monk is the only strong one). Then I read that the boss is written to lose his hostage/dagger at initiative so there goes my idea of surprise attack killing the party leader...
Dwarf monk moves in with a flurry of blows that all miss, then desperately trips the boss as he attempts to nimbly dodge. The boss quick draws up his dagger as he stands up, but off balance so he misses the dwarf monk. The goblin bard inspires courage, then telekinesis a stone free from the crenelations which crithits the boss - the card says it dents his armor enough to break off!. The gnome cleric hits the boss with fear then offers guidance to the goblin bard. Halfling druid tanglefoots the boss.
Dwarf monk gets a hit with flurry of blows, but then gets overconfident and trips himself. The boss drinks a lesser healing potion as that stone really hurt (missed that some crithit cards are normal not double damage), then critically stabs the prone dwarf monk despite his fear (not a nat20 so no card drawn, but I forgot the sneak attack so not dying but that will happen next turn for sure). The brave goblin bard sings a nasty goblin song, then tries to appeal to the boss to stand down or she will sing some more. The boss is not willing to surrender but decides not to kill the prone dwarf monk as he just wanted to frighten people into staying away, gnome cleric range heals the prone dwarf monk. The Halfling druid morphs claws in case the boss attacks.
The dwarf monk is mad, stands up and critically shoves the boss over the crenelation rather than grab him for arrest, but the boss critically grabs an edge preventing the fall. The dwarf monk trys to shove again but instead loses ground to the loose rock and falls prone himself. The boss climbs back up and over on the second try, but loses his dagger in doing so. The goblin bard sings a goblin fight song, then the boss stands down upon further consideration that it is foolish to face the party and a goblin tribe that are now picking up stones themselves, he starts saying wait maybe we can make a deal...
The dwarf monk probably should have used mountain stance, but I think tripping yourself should not apply. Guess we will find out if they take the boss up on his offer.
This was a non-lethal combat by design so rather than just attacks it was made way more fun with tactics, combined with critical success/failures interacting with some critical hits/fumbles draws
