Baha DATA memes

Baha DATA Weapons - 4.6% DA/TA SL 10, 7% DA/TA SL15.

Damage Increase SL15 - Theoretical - 0.07 * 300 = 21 + (0.93 * 0.07 * 200 = 13.02) = 33.02.

Damage Increase SL10 - Theoretical - 0.046 * 300 = 13.8 + (0.954 * 0.046 * 200 = 8.7768) = 22.5768

But HOLD UP. Characters have BASE DA/TA rates. Note that higher base DA/TA rates will devalue the addition of Baha DATA weapons, so the following would be a worst-case scenario.

Base Rates are reported to be 10% DA, 5% TA for higher-end types.

[Base damage magnification - 10% DA, 5% TA]

TA: 0.05 * 300 = 15
DA: 0.95 * 0.10 * 200 = 19
TOTAL - 34 (34% Damage increase)

[Add SL10 Baha DATA weapon - 14.6% DA, 9.6% TA]

TA: 0.096 * 300 = 28.8
DA: 0.904 * 0.146 * 200 = 26.3968
TOTAL - 55.1968 (55.1968% Damage increase)

Damage increase over base: (155.1968 - 134)/134 = 0.1582, or 15.82%.

[Add SL15 Baha DATA weapon - 17% DA, 12% TA]

TA: 0.12 * 300 = 36
DA: 0.88 * 0.17 * 200 = 29.92
Total - 65.92 (65.92% Damage Increase)

Damage increase over base: (165.92 - 134)/134 = 0.2382, or 23.82%

[Analysis (Opinion-based, think for yourself as well)]

PRO

-Significantly more HP than regular ATK/HP Baha option (32% versus 18%)
-Damage increase is direclty multiplicative, as DA/TA will simply take your final attack value and either hit twice/three times.
-DA/TA has other beneficial effects (Meter gain, character-specific effects)

CON

-Single-race only, meaning you may need to make multiple ones to suit your team needs.
-RNG-based. May have limited or no effect at all, or you can score 3 TAs in a row without other buffs.
-No benefit to ougis/nukes

NEUTRAL

-Benefits significantly from skill leveling, which means more fodder investment. Still you're eventually capping that stuff anyway, right?
-Can stack with ATK/HP Baha for 32% ATK/50% HP/7% DA/7% TA, but may not be suitable for your pool. Generally also gives up raw damage values.
-May have anti-synergy with certain skills (Ferry's 100% TA buff directly devalues Baha DATA buffs, for example)


EXTRA - BIRDMAN

Birdman gives 5% TA to the team once 5* and leveled appropriately. How good is this?

[Base + Birdman - 10% DA, 10% TA]

TA: 0.10 * 300 = 30
DA: 0.90 * 0.1 * 200 = 18
Total: 38% Increase

Increase over base: (138-134)/134 = 0.0299 or ~3% increase in damage.

[Base + Baha DATA + Birdman - 17% DA, 17% TA]

TA: 0.17 * 300 = 51
DA: 0.83 * 0.17 * 200 = 28.22
TOTAL: 79.22% Increase

Increase over Base + Baha DATA: (179.22 - 165.92)/165.92 = 0.0802, or ~8%

So yeah, TA increases synergize with each other.
