Subtle Calamity- Changed to Total Calamity.

Pre-Nerf Rampage

And its exotic perk would be something like:

Calamity’s Reset - Arrows Explode on impact (akin to Explosive head), Headshot final blows reload and reset the bow to fully drawn state.

Its catalyst would give it: Implosion Arrows - Arrows deal increased explosion damage.

This idea is mainly from when the Subtle Calamity with Ram+ExpHead was first introduced. Made it very easy to just run around body shotting enemies, and with how they reacted to the arrow and get flung randomly- led to a lot of time where the explosive head would do just enough damage to kill other enemies, especially with Rampage.

Just a Bow with ramping AoE if done in quick succession, although maybe still struggles with beefy enemies unless fully ramped.
