In Dungeon World, one of the classes is called the Immolator. It has a signature move called "Burning Brand". Its description follows:
When you conjure a weapon of pure flame, roll+CON. On a 10+ choose two of the following tags, on a 7-9 choose one. You may treat your INT as your STR or DEX in regards to making attacks with this weapon. The weapon always begins with the fiery, touch, dangerous, and 3 uses tags. Each attack with the weapon consumes one use.
- thrown, near
- +1 damage
- remove the dangerous tag
This makes sense other than the default touch tag. What on earth does that mean? Do you have to touch the weapon before using it (that seems to be true of about any weapon)? Does the weapon have to spend some time making contact with a foe beyond a normal strike to deal damage? What could it possibly mean?
