Beating the Captain without using any weapons (Nuclear Throne)

This time I beat the Captain without using any weapons and only using Crystal's shield ability to reflect the Captain's shots, causing her to damage herself until she dies. This run took 5 tries.

The Captain fires only 2 types of projectiles, both of which deal the same damage to Crystal as to the Captain:
The small shots deal 3 damage per hit.
The large shots deal 8 damage per hit, and split radially into 10 lines of 8 small shots each.

When the large shots are reflected, they are "possessed" by Crystal and deal 8 damage to the Captain; however, when Crystal's large shot splits, the radial small shots are "repossessed" by the Captain, meaning Crystal can be damaged by her own reflected large shots while dealing no additional damage to the Captain (which makes this fight significantly harder). The radial small shots have to be re-reflected in order to deal damage to the Captain.


The Captain has 1540 health, of which AT MOST 35 was removed with the initial hit, which was necessary (from the wiki: "The fight with the Captain will only start when she is attacked." ). This means 97.7% of the damage (1505) was done passively (without a weapon).

I hit the Captain with 40 reflected large shots, which means an approximate total of 395-407 reflected small shots hit the Captain before the end of the fight.

Again, I refrained from taking Gamma Guts and Sharp Teeth for this run, which leaves reflected shots as my only damage output.
