What more is there to say? Pyromania is strong in this one. Along with all the others in the same party. This one is a big rite of passage for murderhobos everywhere. Like the roleplaying requirements for the Drunken Master prestige class. But you too should strive to burn down a tavern. Accidentally of course. No one likes intentional destruction of property when the inhabitants might be people you like. Burning down the ancient ruins filled with undead is fine, provided there's been a chance to loot them properly first.
