<font color="lightblue">Decurion, yes you can backstab with longswords. </font>

It's been awhile since I played a thief character, but I am pretty sure the strength bonus was only tacked on afterward.

you can backstab with any natural thief weapon, which includes long swords... maybe you used a bastard sword or something, or maybe your target was imune to the weapon you used. my thief is only str 13 and I get 5X backstabs around 40 with celestial fury. i dunno bout str bonuses though cause str 13 doesnt get them anyway

Drewal and Rataxes are both correct, the STR damage is not multiplied, but simply added on after the backstab. The only cases where STR is multiplied is when scoring a critical hit. The STR damage would be doubled in this case, giving a max damage range of 84-154 for this particular combo.

Nothing better than a 19STR Assassin [img]smile.gif[/img]

Use Draw upon Holy Might to put it to 25, poison Celestial Fury then whack some unsuspecting fool from behind. Use the ring of invisibility (or the unlimited potions from Alchemy) and repeat.

Ha ha ha.

Traps are cool too. Come on Firkraag, I'm over here. Boom.

Alright, this might just be insanely obvious, but for one, you do have to be invisible right? And two, maybe he saw through your invisiblity like some other creatures do?

BTW, Welcome to IW bro.

strange..my kensai theif never experiences this problem...however yoshimo does. i made yoshi a GM in longsword, and against armored fellows he backstabs for less than expected, but against mages and archers it's perfectly as projected. it could be that the game treats longswords as slashing rather than piercing...?

For those that think I'm not actually backstabbing, I am. I always get the prompt of "Aklar backstabs for quintuple damage" or whatever it says. I normally am hiding in shadows or invisible or whatever. I just find it odd that Valygar backstabs for more damage with a quadruple backstab and he doesn't have GM in Katanas, like my main char has in longswords

here's the reason: Katanas are piercing, Long Swords are slashing. so AC affects the damage of long swords, but not katanas.

AC shouldn't have any effect on the damage inflicted. It is merely one of the factors which determine if a hit connects or not.
