Tower Values range from 0 to 6500
0 to 1080 deals damage (hereby considered active)
1081 to 6499 deals no damage (hereby considered not active)
6500 is turned off and has to be manually turned back on.

The towers continuously increase their value at a seemingly random speed.
Shooting/Spreading at a tower reduces the value by an amount that varies with the frame and probably also the lens.

If a Tower is frozen or burning it does not deal damage.
Somewhere between 1070 and 1080 the beam starts to flicker, when flickering the beam seemingly only deals damage when the game displays a frame that shows the beam active. At 1081 and above it can flicker but i have never seen it deal damage.

Otenko Charge Memory Address: EWRAM 0x00766C
19200 energy needed per tower (76800 in total)

Minimum charging speed: 6 energy/frame (when using the Gun del Hell)
Default charging speed: 12 energy/frame
Maximum charging speed: 17 energy/frame
That can be achieved either by spreading at otenko or using a RSG and topping it off with a spread

Otenko charging times per charging speed
106,66 sec at 12 (no RSG, no spread)
85,33 sec at 15 (full fight with only RSG)
75,29 sec at 17

Otenko does not charge

• during a Hel attack
• when he is down after an attack
• when traveling between towers
• during the summon animation

Different Frames make the charging speed rise to the max at different speeds

• Spread frames are fast
• Sword frames generally seem a little slower than Spread frames
• Shotgun frames require constant spamming but aren't too bad, they bump it to 17 pretty much instantly
• Rotating frames are just bad (they only increase when the spread is covering otenko)
• Guardian seems overpowered

(Note: i don't have a rate of change for the charging speed per frame, it's an estimation from looking at the diff)

Frames with no Effect:

• Fighter
• Knife, Dagger, Gradius, Calamity
• Juggler, Wizard, Beatmania
