Explosive Crossbow

The Explosive Crossbow is a crossbow-type ranged weapon which fires arrows that damage enemies in a small area. The projectile does critical damage to anything struck by the bolt. The secondary attack is a melee strike which deals critical damage to foes directly struck by it, while pushing others away, similar to how Wave of Denial behaves.

Location
The blueprint for this item in the Promenade of the Condemned is locked behind three Enigma doors which require Gardener's Keys to be opened, they can be found in the following locations:
 * There is a place to dive through the ground using the Ram Rune where one Gardener's Key can be found.
 * There is a tower to find that you can climb up with the Spider Rune where another Gardener's Key can be found. Alternatively, the key can be grabbed with your head using the Homunculus Rune.
 * There is a potted rose that is on the ground somewhere in the Promenade, dive three times and it will give you the last Gardener's Key
 * If done correctly, stomping it once will cause the rose to yell "Hey", the second time "What the......?" and the third stomp will cause the key to spawn.
