After some good comments I decided to mix up the gameplay a little for more strategic plays!

General

- weak core is "removed" but the effect is still there, you just need to hit the heart core with a quintuple to trigger it!
- bandage core added, works similar to heart core, but is consistent between rounds and monsters. after reaching a threshold of 21 in value, heal 10 hp
- Flee for free loot is removed and replaced with a bandage core loot buff
- changed sound on spin

Balance

- boss buff -> removed attack reduction on breaking shield
- thrash blob armor 13 -> 15

- fish attack 4 -> 6
- bear attack 7 -> 8
- thrash panda attack 7 -> 9 | armor 10 -> 11
- fly armor 2 -> 0
