Hellfire

Hellfire is a warlock spell card, inducted into the Legacy set, formerly from the Basic set.

Strategy
Hellfire is one of the strongest board wipes in the game but its use must be carefully weighed. It is most obviously advantageous when the player has far fewer or less valuable minions on the board than their opponent, or is able to more easily recover from the board wipe, whether through sticky minions such as Piloted Shredder, or due to strong card advantage. It can also be useful for activating effects like Nerubian Egg.

It is also important to remember that Hellfire not only damages all minions on the field, but also yourself and your opponent directly. This can allow it to be used as a nuke to push past Taunts, but can also make its use unwise by lowering your Health too much. Notice that if Hellfire simultaneously deals fatal damage to both heroes, the game will end in a draw.

Lore
is a channeled spell which causes a small amount of damage to all nearby hostile targets - as well as the warlock themselves - every second while it is being channeled. The spell is commonly used to clear weak "trash" mobs, although the warlock will likely need healing in order to ensure they do not themselves succumb to the spell's damage.
