Potion of Heroism

Potions of Heroism are potions throughout the that magically improve the consumer's chance of landing a hit during combat while simultaneously raising their health, both for a duration of two hours. Only warriors and monks can use them. They are sold by many merchants, can occasionally be found in e.g. chests and are carried, sometimes used, by a small number of characters.
==Gameplay==
The description of the Potion of Heroism is not exactly accurate: In addition to warrior classes, the, monk can also use it, while the wizard slayer cannot.
After consuming the potion, the warrior's THAC0 is set to 90% of the current base. Thus, THAC0 = (THAC0 * 90 / 100) - Example: A 7th level Warrior has a Base THAC0 of 14. After quaffing the potion THAC0 = (14 * 90 /100) = 12.6 - the game engine rounds this to 12. Therefore, the warrior's new Base THAC0 has improved from 14 to 12.
Also, after consuming the potion the warriors base Hit Points are multiplied by 110%. The game engine will round small remainders to the nearest whole number.
These effects apply for ten turns, or two in-game hours. 
Regarding Dispel Magic, this potion is akin to a 6th level caster in BG1 and 10 in BG2. 
The HP bonus (but not the THAC0 bonus) stacks with itself if the potion is used repeatedly, and also stacks with the HP bonus from the Potion of Power, but only the last THAC0 bonus from both potions is applied and it does not stack (so if using both, Potion of Power should be used last since it has higher THAC0 bonus).
