First Turn

During the first turn of each Battle Windows enemy, there is a 25% chance for Battle Windows to attack first. This is a notorious point of chance in the run where time can be lost if Battle Windows attacks first.

When Battle Windows attacks first, time loss can vary depending on the attack that is done. The worst possible luck is having an enemy shield on their first turn, which requires a whole additional turn to defeat it.

In specific circumstances, it is actually beneficial to have Battle Windows to attack first, but this is typically only done in TAS. An example of this is using Suplex while fighting Red Dragon. By having Red Dragon attack first, Kirby can grab its attack and defeat it in one turn.

Procedure

Calculating the outcome for first turn attack uses one RNG number.

Slime and Magician: 64 < RNG < 127: Battle Windows attacks first Else: Kirby attacks first

Puppet and Dark Knight: 128 < RNG < 191: Battle Windows attacks first Else: Kirby attacks first

Red Dragon: 192 < RNG < 255: Battle Windows attacks first Else: Kirby attacks first

Ability Appearance

When it is Kirby's turn to attack, abilities have a chance of appearing on each side of the screen. Several random numbers are used during this process. This calculation is different from power calculation in The Arena rest area.

Procedure

Flowchart depicting how Battle Windows uses RNG.
  • 1.) Determine if a power will appear on the right side:
    • 64 < RNG < 127: Power appears
    • Else: Does not appear (Skip steps 2 and 3)
  • 2.) Determine which pool to choose from:
    • 0 < RNG < 63: Pool 1 (Sprite number 90)
    • 64 < RNG < 127: Pool 2 (Sprite number 91)
    • 128 < RNG < 191: Pool 1 (Sprite number 90)
    • 192 < RNG < 255: Pool 2 (Sprite number 91)
  • 3.) Choose a power from the pool chosen:
RNG Ability Pool 1 Ability Pool 2
0 - 21 Fighter Stone
22 - 42 Plasma Cutter
43 - 63 Hammer Wheel
64 - 85 Beam Jet
86 - 106 Bomb Ice
107 - 127 Sword Parasol
128 - 148 Hammer Fire
149 - 170 Bomb Suplex
171 - 191 Plasma Ninja
192 - 213 Sword Yo-yo
214 - 233 Beam Mirror
234 - 255 Fighter Wing
  • 4.) Determine if a power will appear on the left side:
    • 128 < RNG < 191: Power appears
    • Else: Does not appear (Skip steps 5 and 6)
  • 5.) Same as step 2
  • 6.) Same as step 3

Notes:

  • If no abilities appear for 3 consecutive turns, abilities will appear from both sides on the next turn (steps 1 and 4 are skipped).
  • In the rare circumstance that abilities appear on both sides, and both sides contain the same ability, step 4 will be repeated again after step 6. This will continue to repeat until either both abilities are different, or only a right side ability appears.
