Back to the main thrust of the topic, how is the "attack twice" mechanism, actually supposed to work?
Second Edition: Game System: Treasure Card wrote:Heroic Brew
A leather bag hanging on the wall holds a potion. It is a Heroic Brew. The potion may be taken just before you are about to attack. Any player who drinks the potion will be able to make two attacks instead of one, for one turn only. The card is then discarded.
Taking the simplest first "Heroic Brew" what are the questions?
A) Do both attacks have to be against the same target?
B) Can you split the attacks between movement i.e. attack, move, attack?
C) Can you attack once, with a particular weapon then switch and attack again
I don't see anything in the text that suggests that both attacks have to be against the same target or different targets, nothing that indicates that you can or can't put movement between the two attacks or switch weapons between attacks. So I can see two possible interpretations here, and no evidence to suggest which is correct, although at this point I favour (1) but only because this potion feels like it increases your speed of attack, so this seems to be contradicted by letting a hero attack rapidly, move at standard speed, then switch to a crossbow and attack rapidly again.
1) Single Attack Action containing two attacks - this would mean you couldn't move between attacks and couldn't switch weapons between attacks
2) Two Distinct Attack Actions - this would mean that you could move between attacks and switch weapons
Second Edition: Game System: Quest Treasure Card wrote:Orcs Bane
The sword, Orcs Bane allows you to roll two combat dice in attack. You may attack TWICE if you are fighting Orcs.

Orcs' Bane presumably uses the same mechanism (for consistency and simplicity) but adds the restriction that the attacks must be against Orcs
Again same two interpretations available (1) and (2) above, but in this instance I think there is a problem if we assume option (2). Picture the scene, you are armed with Orcs' Bane and have two Orcs adjacent to you, you attack the first once, killing it, you then move to your second attack action (permitted as you have Orcs Ban and you are attacking Orcs), as part of your second attack action you decide to switch to your Battle axe. We now have something of a logical loop, you are now no longer wielding Orcs Bane so you don't get your second attack action. Which means we need to roll this back and reverse the action in which you decided to switch weapons, so you are now back to wielding Orcs Bane, so you now CAN take a second attack action. You decide to switch to your Battle axe... have fun coding this one into a computer game!
Therefore for the sake of simplicity I will assume that interpretation (1) is the intended one
Lets see if this checks out for our third contender, the Orc Shaman's Orc Berserker spell.
Second Edition: Wizards of Morcar: Spell Card wrote:Orc Shaman Spells: Orc Berserker
The Sorcerer may choose one Orc within his line of sight to be filled with immense strength and vigour. That Orc may then move twice and attack twice during that turn only. Discard after use.
Applying our interpretation (1) logic here would mean the monster under the influence could attack twice in one action and then move (twice), OR move (twice) and then attack twice in one action
This seems to work fine and would be exactly the same effect as our Orc quaffing Heroic Brew and Potion of Speed at the start of his turn, he could move twice (double amount) and attack (twice) OR attack twice and move twice, so I think all is well in the world, so far.
How do they stackAs both allow you to attack twice, I'm not sure that they do stack. You attack against an Orc, then you attack another Orc. This has satisfied Heroic Brew (as you attacked twice) and satisfies Orcs' Bane (you attacked twice against Orcs), no further action required?
Rule Clarification: Attacking Twice wrote:Some items allow a character to attack twice instead of the usual once. In this instance both attacks are considered part of one single attack action, so you cannot split the action by moving in between, neither can you switch weapons between attacks, it is a single action comprising of one attack followed rapidly by another using the same weapon. You may direct your attacks against different targets provided that they are both valid targets. Defence is handled as standard. Using more than one item that gives you an "attack twice" bonus does not stack, for example attacking Orcs with Orcs' Bane whilst under the influence of Heroic Brew means that you will get two attacks only as this satisfies the criteria for both effects
For those who think that Orcs Bane is too "weak" (I'm not sure that there is any minimum strength for a magical weapon) it is the same strength as Heroic Brew so is that also too "weak" or is the perceived issue that Orcs bane is too restrictive in its application "Orcs only". if that is the issue then I would agree expanding out the targets to all Greenskins, Orcs, Goblins, Orc Warlord and so on would make perfect sense. Another option would be to allow your Wizard to use short swords (sacrilege!) and then this becomes a useful hand-me-down sidearm for him in later quests...or both.
